ABSTRACT: The stimulated Raman scattering was investigated at an
excItation power
just above the 10ireshold using the following three different
setups: 1) a Raman
cell in the resonator of a laser; 2) a longitudinal selective
resonator (the term
used by the authors for the case when the Raman-laser WV ator is in
the direction
of the ruby laser resonator); ird 3)a transverse selecti f6sonator
(the term used for
the case when the/Raman laser resonator is rotated 90* from the
direction of the
axis of the rubyllaser, i.e., a 90* off-axis Raman laser resonator).
In the first
setup the gi7a_n_t~ulses were produced by a ruby crystal. Using two
variable-trans-m
mission-coefficient filters (transmission coefficient 30-50% at A =
694 mp) the
effective intensity of the 30-300 nsec-duration pulses in the
resonator reached
100 Mwt/cM2. The maximum energy per pulse was 3-4 j. Two dielectric
mirrors with
a transmission coefficient of 0.4% at X - 694 mp, 0.8% at X 745 mp

A 875 m
(second harmonic.) were used in the experiments. The SRS in benzene
had thresholds
for a specified length of the Raman cell (i) and the laser input
power. No SRS
was observed at .1 < 2; however, SRS was stable for 5 < 1. < 60 cin.
The threshold
power decreased almost linearly with increasing 1. At 1. - 60 cin the
efficiency of
energy conversioa reached 10% of the power in the cavity. It was
observed that
an increase in the energy of the pulses from the ruby 1.5-2 times
above the
threshold resulted in a three-order increase in SRS. In the
longitudinal selective
setup the qdditi'onal reflector between the.ruby rod and the Raman
cell had a trans-
mission coefficient of 90% at A - 694 mp, 10% at X - 745 V, and 1% at
X = 805 and
875 mp. In this mode of operation the efficiency of energy conversion
was at least
as high as that In the previous case. Two-higher harmonies at X = 745
and 805 mu.
which reached saturation at lvlO% of the input power were observed.
Results similar
to those of the :[ongibx1in61,.setup, were achieved with a transverse
sdective setup. HMMver*
SRS was achieved in a Raman cell the length of which along the laser
beam was only
1 cm. Stimulated Brillouin scattering in benzene was also observed in
this setup.

1he maximum
the 20-200 nuee-duration pulses in the resonator reached 100
Mwt/cm2. T
energy per pulse was 5-6 J. Two dielectric mirrors 01 and 02 with a
transmission
coefficient of 0.4% at A = 694 mu, 0.8% at A = 745 mu (the
fundamental SPS line in
benzene), and 40% at A = 805 mV (the first harmonic) were used in
the experiments.
The sensitivity of the detectors was sufficient to register 10-4 of
the energy of the
laser pulse. The setup shown in Fig. la was used to investigate SRS
in benzene. It
was observed that an increase in the energy of the pulses from the
ruby laser 1.5-2
times above the threshold resulted in a three-order increase in SRS
at the funda-
mental frequency. Saturation was reached when the intensity of SRS
was about 10% of
the energy input, at which time the second harmonic whose energy
output quickly
reached the level of SRS at the fundamental frequency (at
saturation), appeared.
When the second harmonic reached saturation the duration and the
intensity of the
laser pulses decreased sharply due to the reverse effect of SRS on
the ruby laser
pulses. When the length of the Raman cell (1) was increased, the
threshold power
and the pulse energy required to achieve SRS decreased. Also, the
larger the cell,
the smaller the energy above the threshold at which second
harmonics were generated.
The SRS was stable when I was between 5 and 60 cm. In the
longitudinal selective
setup (Fig. lb) reflector 02 replaced 04 and the transmission
coefficient Of 03 Was
very high at A = 694 mp and was at a minimum at X = 745 mv. The
gain of SRS at
1 = 5, 20, and 60 cm was at least as high as in the previous case,
although the pump
power and the pulse energy required were considerably smaller. For
example, when the
output of a ruby laser pulse of 30 nsec duration was 40 Mw (1 = 20
cm) three 10 MW
SRS pulses of 20 nsec duration were observed in the Raman laser
cell. Similar re-

ABSTRACT: The authors observed the occurrence of birefringence in
potassium vapor
under the influence of the electric field of ruby laser emission
by passing simul-.
p ttnd from a ruby laser through a vessel con-
taneously light from a potassium lam
taining saturated potassium vapor at 150C. At this temperature,
the vapor absorbed
approximately 50% of the resonant light from the lamp. When the
laser pulse was
applied ('( D nsee duration), a clear-cut signal vas observed,
indicating an increase
in the re"-onant radiation from the lamp passing through the
vessel. At a laser
emission power density of the order of 5 Mw/crf the amplitude of
the signal corres-
ponded to transmission of several times ten per cent of the
intensity of the light
from the .1.amp. The greatest signal vas observed when the lamp
radiation and laser
emission clectric fields were at a 45* angle. There vae no signal
when this angle

wan frozen out) vhen the potassium lamp was turned offp or when the
filters used to
polarize the light were removed. The latter, togetherwith the
dependence of the
signal on the angle between the electric vectors, proves -that the
observed effect
is due to birefringence induced by the laser pulse because the shift
of the absorp-
tion line in the laser-emission electric field has different values
when the elec-
tric vector of the light is parallel and perpendicular to the vector
of the laser.
The value of this line shift is calculated and the wavelength
dependence of the
laser emitision intensity required to obtain a signal of prescribed
magnitude Is mea~-
sured and found to be linear in the wavelength difference between
the resonant transi
tion and the laser emission. This agrees with the theoretical
calculat4ons. The

ABSTRUCT: The authors discuss attempts to reconcile several
contradic-
tions in the mechanism customarily proposed to explain the
excitation of
luminescence centers by electric field pulses, and in particular
the
fact -that according to the currently held hypotheses a difference
should
exist between luminescence produced by unipolar and bipolar
pulses, al-
though recent experiments by one of the authors (Boncb-Bruyevich
et al '
Opt.-i spektr. v. 11, 87, 1961) have proved conclusively that no
such
difference exists. Several hypotheses advanced to explain this
contra-
diction are briefly discussed and it is concluded that the reason
why
the symmetry of the luminescence distribution is not connected
with the
symmetry of the external voltage calls for further research, as
does the.

question of the electroluminescence mechanism in general. This calls
Ifor a ~?eview of the notion that the impact ionization is brought
about
Iby a local rise in the field concentration near inhomogeneities. Orig.

provided the same glasses and resonator mirrors are used. The
marked disadvantages
of the GSI-1 are the comparatively low effectiveness of its
eight IFK-2000 standard
flashlamps; and its consequent low efficiency (0.3-0.4%), and
the saturation of the
lamp characteristics. These disadvantages were partly
remedied when a rectangular
cross-section spiral flashlamp was used instead of the
IFK-2000 lamp. This led to a
twofold increase in the laser efficiency and increased pulse
energy of up to 100 J.

cited absorption bandsi.in ruby, the transverse absorption

and 0.04% Cr 3 by weight
The ro'd ends were masked leaving rectangular I x 3 mm
windows. The 400 )1 pumping
2ight was provided by a pulsed xenon lamp excited by a 500 mf
bank of condensers. The
.pst radiation was generated by a lamp that has a continuous
spectrum in the near UV,

double monochromater, and

ABSTRACT: The authors have investigated theoretically and
experime, ally the phen-
omena accompanying the disruption of metals by focused laser
beoms.,J~alin the pre.-,ent
paper there is considered the case of a laser producing
aDproximately
1 millisec pulses, each consisting of a sequence of
approximately 1 microsec s- 'ikes.
The phenomena accompanying disruption of metals by~ginnt laser
pulses will --;. discussed
in a future paper. In the theoretical part of the paper, fluxes
of )_U'- .o 1016erg/CM2
sec on an approximately 1 mm diameter spot are considered. It is
shown that under
these conditions the transport of energy in the metal by hoot
conduction during the
duration of,Ia spike is negligible, and the problem of the
vaporizntion of the metal is
accordingly treated in one dimension. Formulas are derived, and
curves are presented
for different metals, relating the energy flux in the laser
beam, the temperature of
the metal surface, the erosion rate of the metal surface (i.e.,
the rate of increase

in the depth of the hole), and the velocity and pressure of the
jet of E~L~ ~r.The
temperature of the metal surface is not equal to the boiling
temperature, as was erro-
neously assumed by J.F.Ready (J. Appl. Phys., 36, No.2, 462,
1965). The theoretical
relations were tested by experiments on some 16 metals and
alloys, using neodymium '
glass lasers producing up to 300 J pulses. The laser beam was
focused with a lens onto
the parallelepipedonical specimen and the disruptive process was
recorded cinemat-
ographically at 105 frames per sec. In most of the experiments a
glass plate was
cemented to one face of the specimen and the laser beam was so
directed parallel to the!
glass-metal boundary that about half of the beam passed freely
through the glass and
the other half penetrated into the metal, vaporizing it. In those
experiments the
process was photographed through the glass. The mass of metal
removed by the laser
pulse was determined by weighing the specimen, and the impulse
due to reaction of the
metal vapor jet was measured. The experiments were in qualitative
agreement with the
theczy, and quantitative agreement in order of magnitude was
found. The authors feel
that development of a more accurate theory would not be
worthwhile, owing to the large
variations between different lapers. Three stages were
distinguished in the disruption!
process: in the first stage- he temperature of the metal surface
increased at the rate!
of approximately 10 Itc; in-the second stage metal was vaporized
from the
specimen and a hole was formed in it; and in the third stage a
pressure of 102 to 10 3
atmospheres developed within the hole and a powerful Jet of metal
vapor issued from it

lost by the specimen was approximately equal to, but in most cases
somewhat less than,
the heat of sublimation of the metal. An appreciable mass of the
metal was ejected as i
liquid. Orig. art. has: 9 formulas, 9 figures, and 2 tables. (151

.ABSTRACT: A study was made of-a-traveling-wave external-feedback
neodymium glass
laser, the experimental setup of which is shown in Fig. 1. The
external cavity
Pons'isted of four mirrors arranged in"a rectangular pattern (1.5
x 0.5 m). The
output mirror.(5') was 80% reflectIve and the three other
mirrors.were 99% reflective.
The active medium was a cylindrical glass rod 240 mm long and 25
mm in diameter.
The laser was pumped by two IFK-15,000 flashlamps fed from a
condenser bank having a.
total stored energy of 30 kj. A Faraday-effect cell, consisting
of a quartz plate aann
a polarizer (six plane-parallel Brewster-angle plates) was used
to achieve traveling-
wave operation. A D'FS-8 spectrograph (dispersion 6 X/mm) and a
Fabry-Perot inter-
-ferometer were used to observe the emission spectra of the laser
at various pumping
'levels and with the Faraday cell in and out of the feedback
circuit. It was shown
that the emil3sioyl spectra of traveling-wave lasers are
virtually line spectra and

ABSTRACT: The authors experimentally investigated the frequency
shift of the optical
resonant transitiqn 4S1~2 - 4pl/2,3/2 of potassium (principal
doublet). It can be
be shown that theexpec ed frequency shift of this transition is
connected principallyl
with virtual tranqition induced by the laser pulse from the ground
level (4SI/2
4P, 2 3/2) and the excited level (03/2 - 6S1/2). The first pair of
transitions is
sti(l'.sufficiently far from the resonances (the transition
wavelengths are 7665 and
7699 A, that of the laser is 6943 A). The 03/2 - 651/2 transition is
much closer
to resonance 0. = ~16939 A)- In wpite of this, all these transitions
make comparable
contributions to the sought frequency shift of the investigated
transition, owing to
the difference in the oscillator strengths. It is important that the

excited levels are shifted here by the ruby-laser light in opposite
directions.
In the. experiment Iight from potassium lamp 1 was passed through
vessel 2 with
potassium vapor saturated at 100*0 (see the figure). At the
selected temperature,,
the vapor absorbedl about 80% of the lamp's resonant radiation.
Transmission of
light by vessel 2 was expected to increase during the action of the
pulse from laser
3, provided the resultant transition frequency shift is
commensurate with the line
width of the lamp radiation (it was assumed that this line was
broader than the
absorption line of1the vapor). The transmission of the resonant
light was recorded
with a hotomultip~ier whose output was fed to a pulsed oscilloscope

The scattered las r light in the registration channel*was reliably

laser pulse, is
accompanied by scittered radiation with spectral components lying
in the region of

I was made to pass through an auxiliary cuvette 6 filled with
potassium vapor and place
between crossed polaroids 5. A local magnetic field of
approximately 2 kOe was
applied to cuvett6 6. The magnetic field produced, besides
splitting of the absorp-
tion line, strong;radiation of the plane of polarization of the
light, but only in
the nearest vicinity of optical resonance. By magnetic field
intensity- selection,
the system was ma e to transmit almost all the resonant linej and
to absorb the
extraneous light.~ The entire apparatus behaves like a
high-transmission optical
filter with a bandwidth on the'order of 0.1 cm-1. Under the
conditions described,
a distinct signal was recorded, evidencing a decrease in the
absorption of the
resonant light bythe potassium atoms in vessel 2 during the time of
action of the
laser pulse (20 n~-ec); the laser operated in the monopulse mode by
using bleaching

ABSTRACT: The operational characteristics of a neodymium glass laser
with a resonator of spherical mirrors were investigated for varying
distances between the mirrors. The introductory theoretical
considera-
tions Droceed from results obtained earlier by other authors (e.g.,.
Boyd'and Gordon, Bell. System. Techn. J., 40, 2, 1961, 489) and
define
the regions occupied by certain modes as determined solely by the
dis-
tance between the mirrors and the radius of their curvature.
Further,
the beam divergence is assumed to be determined by the divergence
of the
highest mode in the system. The minimum divergence is attained when

distance between the mirrors equals the radius of curvature of the
mirrors,
corrected for the presence of a rod having a certain length
and refractive index. Experiments were conducted with various rod
and
mirror dimensions, but measurement data are presented only for
mirrors
with a 150- cm radius and rods 50 cm long and 2.5 cm in diameter.

was done since the dependcies in all cases have the same character.
The output energy varied between 200 and 500 J. The.os'cillograns
of the
output pulses show a high degree of uniformity in pulse anplitude,

proportional to the square root of the instant pumping power, and

increase gradually when the distance between the mirrors is reduced
below the optimal. This increase, however, never exceeds the
frequencyl
at the optimum by more than 1.4. The beam divergence increases to
either side of the confocal position, in good agreement with the

retical relations. The beam brightness is at a maximum when the
dis-
tance between the mirrors is optimal. The cross-sectional energy

tribution within the bean is rather uniform and is indeDendent of

Abstract I -The physical concept of a heterogeneous surface., in
adsoprtion processm
is elucidated. The electron processes occurring during adsorption.,
and., which may lead to certain deviations from the Langmair
adsorption
laws, are discussed. It is stated that farther development of the
theory of heterogeneous surfaces depends upon the knowledge of the
physics of heterogeneous surfaces,, i.e.. knowledge of the elementary
mechanism of adsorption processes. Nine USSR references (1935 -

ABSTRACT: Weakly excited states of a semiconductor having atomic
lattice, with no elec.
tric or magnetic field, are examined by the method of elementary
excitations
("dyads" and holes). Under the condition of even numb 'er of
electrons la the
norwal state, a Fermi type spectrum results in the frame of an
exciton polar
model. Multielectron-theory equations do not differ from the
unipolar-theory
equations; for that reason, the elementary excitations behave like
the free
electrons in the zonal theorythe fact substantiating the conclusions
of the
latter re extra electrons and holes. The behavior of the extra
electrons and
holen in electric and magnetic fields is determined from the
viewpoint'of the
multielectron theory. Again, the equations obtainod do not differ
from those
in the monoelectron model; elementary excitations in this case do
not differ
from the extra electrons of the zone theory. Considered are also the
energy
spectra of junction-metal bearing materials. Bibliography: 19 titles.

Discussion of V. 1. Lyashenkols paper, The reaction studied by
Lyashenko is exothermic. It can be assumed that a local over-
heating takes place on the surface. The resulting diffusion of
oxygen from the surface into the space increases markedly.
Since Lyashenko used 2,A4 -thick films, the entire space can be
"impregnated" by acceptors at the expense of a decrease of
their
number on the surface.

Studies conducted by the authors have been discussed from the
viewpoint of the concept of "nonuniform surface" which take
place during adsorption may result in deviation from Langmuir's
regularities. The concentration of free atoms In semiconductors
depends on temperature and concentration of the admixtures in
the adsorbent crystal. When the electrons in the conduction
zone
;f the adsorbent surface act as adsorption centers, their
number
depends on the ritimber of atoms adsorbed. Not only electrons,
but
lattice defects as well may act as adsorption centers. The
distribution functions is a characteristic of the entire
system,

With reference to the paper by Roginskiy the author states that
what is involved here Is a problem of quantum mechanics and the
calculation is applied to the simplest type of model. The lack
of quantitative quantum-mechanic calculations for more
complicated
molecules does not discredit the proposed theory. In the case
of "adsorption on the electron", the adsorption centers are
restored on the surface, i.e., In place of the electrons
combined during the adsorption, a new electron comes from the
inside of the crystal. ThIs was demonstrated by F. F.
Vol'kenshteyn.

Title : On the formula for the volt-ampere characteristics of n-p

Periodical: Zhur. tekh. fiz., 25, No 8 (August), 1955, 1520-1521
Abstract : The authors discuss the well known volt-ampere
characteristics formula which
is derived on a theoretical basis. They state that the small
amount of ex-
perimental evidence available indicates a resaonably close
harmony between
theory and fact. They assert, hawever) that in certain ranges the
formula
departs too much from observed values to be of much value. They
introduce
a factor which they claim will make the formula much more
accurate*in these
critical ranges. They suggest further experiments to establish
the validity
of their assertions.

Abstract :Resume of a lecture. A method of approximation
is proposed,
based on the approximate solution of the equations for
the
green's function in the classical external field (the
latter
is aokumed ~o be slowly varying). 'the ihethod is used
to ex-
amine the problem of a strongly degenerate non-ideal
Fermi
gas. It is shown that when the ifteraction is taken into
account (outside the framework of-standard perturbation
theory),
the distribution function of the Uectrons by momenta in
the
ground state does not have a purely step-like cha cter.
This
means that in this system at absolute zero there are
current
carriers with momenta that exceed the limiting Fermi
momentum.
The spectrum of the elementary excitations in a given
system
is also considered.

Abstract The character of the spectrum of elementary excitations

tic,, havi-rig a "lattice that ccntains some structural
defect.9, was
studied within- the framevork of the exchange model. It was
shova that
defects of a definite type play the role of "demagnetizatioi,
centers,"
namely,, spins that are orierlted in opposition to the
magnetization direc-
tion are localized aear these defects. The dependence of the
magnetiza-
tion. on the con-centration of the structural defects was
calculated at
satuxation, and at the Curie point. The results axe applied to

tigation cf the ferromagmetism. of ferrites, solid solutions,

As the problem concerning the general form suited for all
temperatures Jis very
complicated, the present work is confined to the limiting cases
of high and
low temper-%tures; (in the second case a semioonductor at
absolute zero is con-
.cerned). A semiconductor with independent conductivity and with
spherical sur-
,faces of constant energy is investigated here, on which
occasion only inter-
action with the acoustic oscillations of the lattice is taken
into account, For
tthe conduction electrons and for the holes one and the same
coupling constant
is assxmed. This model, of course, is little suited for accurate
computation.
but essential conclusions do not depend on these details. Among
the aforemen-
tioned items there is no interaction with transversal waves~ The
LAGRARGIAN of
the interaction of the electrons with the longitudinal acoustic
oscillations
of the lattice and the coupling constant g are explicitly
written down. All
operators of interest here are diagonal with respect to the spin
indices.
The semiconductor at absolute zero: The "one-partiole density
matrix" for
electrons'and holes at absolute zero is found in the easiest way
by computing
GREEN'S function for the electron field which is in interaction
with.the

phonons. The equations of condition for GREEN'S function of
the electron are
given. By development in series with respect to the powers of
the ooupling
constant a, 'linear equation for GREEN'S function is obtained~
The very Volumi-,
nous solution of this equation is explicitly written down,
Like in the case
of the undisturbed problem two permitted zones which are
separated by 9 for.-
bidden domain are obtained here. Thus the excitation spectrum
is of typically
semiconductorlike shape and the qualitative statements of the
zone theory are
confirmed for this case. However, because of the interaction
between electrons
and phonons the density matrix is by no means of 11steplikell
character. kn A-x,.
pression for the evaluation of the effective concentration of
the charge
carriers in the ground state of the investigated semiconductor
is given..
The homoepolar semiconductor at high temperatures: This last
paragraph in-
:vestigates, the equilibrium properties of a system of
conduction electrona
(and holee.), which are in interaction with phonons. According
to the author's
opinion this is the basis for the development of the theory
without the help
of the kinetic equation.

It is interesting to investigate the general properties of
GREEN'S functions
which are set up independently of any approximation methods.
In the nonrelati-
vistio theory there are certain complications which are
connected with the
,lacking of LORENTZ invariance. However, even in this case
certain analogous
spectral problems exist, which is proved here. For reasons of
correctness a
system with many elgetrons is investigated here. Transition of
systems with
*.BOSE particles presents no difficulties. With the help of
certain ansatzes

easily possible to find the excitation spectrum by comparison

is advisable to introduce yet another GRMNIS function which

expresses the "pair-like" character of the excitations.

The present work does not give a survey of the present stage of
development
of the theory of semiconductors, but merely of the works actually
submitted
during the sessions of the theoretical department of this
All-Soviet Con-
ference. In the course of 5 sessions of the Department for the
Theory of
Semiconductors 13 lectures wcrg delivered which may be divided
into the follow-
ing classes: Theory of the stationary states and kinetics of
electron processes
in semiconductors.
I. The Theory of the stationary States of Electrons in crystal
lattices:
Most of the works in this class are connected in one way or
another with the
consistent consideration of interaction between electrons and the
lattice on
the occasion of the investigation of the kinetics of phenomena
and of the
equilibria of the system.
11. The kinetics of the electron process in semiconductors: The
works be-
longing to this class may be subdivided into the following
groups: a) Theory
of the scattering of current carriers in semiconductors. b) The
phenomeno-
logical kinetics of electron processes. a) The physical theory of
the re-
combination of current carriers.
