ABSTRACT: The possibility of fabricating electrM.;beam-pumped
semiconductor lasers
generating. in the ultraviolet spectral range, is discussed. The
analysis is* limited.
to direct Interband transitions.and does not include the case when
carriers must be.-
treated as polarons. It is.shown that the lifetime of excess carriers
with respect
to interband transitions,accompanied by emission of a photon is
inversely proportional.,'
to the energy 4idth of the forbidden-gap." -The lifetime of
radiationleis transitions
.is thus neglected in the analysis'. Expressions are derived for the ~
minimal pump
power and the optimal duration of the excitation pulse. It is
suggested thathigh~-
purity ZnS,.aluminum andboron phosphides, corundum, and other wide-gap
semiconductors,-
should be tested for laser action in the ultraviolet by means of
electron beam ex-

ABSTRACT:'.Laser action is reported in CdS excited by a ruby laser at
77X. Since the
energy.of photons of incident radiation (A =.1.T8 v) is smaller than
the width of the
forbidden gap (2.5 ev), two-photon absorption was,responsible for
laser action. A
5 x 3 x.3~mm sample forming a Fabry-Perot cavity was'excited by
radiation from a 1--j
ruby laser (pulse.duration 'u50 nseic). The emission spectrum from
CdB at various
pump densities (see Figo.1) is .similar to that of
electron-beam-pumped CdS. The
broadening of the oscillation line with higher pump power was
attributed to an in-
;crease in the number of modes; however, a resolving power of I did
not make it pos-

including the'three'
following processess- resonance-absorption of lij;ht by the
semiconauctor,resulting
in tho formation of electron4ole pairs; induction radiation of light

ABSTRACT: -The recombination:radiation of 1 x 2 x 3 mm samples of
a-SiC with
polished sides excited, by a bean of 2004ev electrons was
investigated '~t a tempera-
ture of 60K.- The electron beam was either perpendicular to the large
face of the
sample. or at a 45* angle to it. The bean's penetration depth was
determined to be-
-120 U.- The emission spectra,of three of the siam Ila are shown in

j ABSTRACT: A theoretical Investigation Is made of the change in the
shape ofa
L? pulseffom a laser during nonlinear amplification. The assumption is
madethat
pulse duration is considerably longer than the transverse relaxation
time of the
medium. An expression is'derived'for the pulse velocity-in such a
medium as a
functioh: of the shape oftbe initial pulse. In the case of the
exponential leading-
edge, this expression,.4hich appiies-to"the 'general case when the
velocity pulse
varies with the the leading edge, reduces to. the
-displacement ofthe pulse along
one derived.by Basov et al. (AN SSSR, Daklady" v..165, no. 1, 1965, p.
58).
It is'shown that it is possible to predict uniquely the, change in the
shape:of the
pulse of light during nonlinear amplification or even the shape -of
the ultrasonic
pulse in a two-level phonon maser ampli-fier.".if the shape of the
initial pulse is
known. Orig. art. has*. 8 formulas and 3 figures. [CS)

a highly heated beam of molecules in allowed to escape to a vacuum

librium radiation is much smnller than (Ep - Em)/k (Fp and Em are
two molecular levels

ABSTRACT: The spatial and temporal development of a giant pulse of a

laser in a transverse direction and the effects of the cavity on it
were investigated
experimentally by means of the setup shown in Fig. 1. A ruby rod 9
mm in diameter
and 120 mm long with dull lateral surfaces was placed in a reflector
with a helical
IFK-15000 flashlamp. For an 8-ki pump the gain per pass was
approximately 12. A
1.5-j single laser pulse was generated with a duration of 10-15
nanosec. Q-switchlf~_
was done by means of a Kerr cell or a vanadium phthalocyanin
solution. The exponen-
tial results indicate that generation commences in the center of the
crystal an

ABSTRACT: The differential equation for the intensity of laser
emission, which In the
case of solid-state lasers reduces to an equation whose stable
limiting cycle cor-
responds to undamped oscillations of t 'lie laser emission
intensity, is solved analyti-
cally. It is shown that the solutions obtained approximate
quite closely the phase
trajectories of the system in a case of large depth of
modulation. The solution con-
sists of two parts. 7he first corresponds to a slow motion when
the active particles
accumulate and the amplitude Increases relatively slowly. The
second represents an
increase in amplitude followed by a release of the stored
energy by radiation during
a short pulse. The analytic relations obtained are used to
calculate the parameters
of a scheme proposed by the authors (Paper at Scientific
Congress in Leipzig, March
1965) to obtain short light pulses (Fig. 1). The periodic
solution of the equations

ABSTRACT: Stimulated emission of InP diodes in the 9060-9080 i
region was compared
with that of their GaAs counterparts (see Table 1). InP bars were
prepared by the
directed crystallization method in the form of large-size
polycrystals grained in the
direction of the bar axis. The bars were tellurium-doped with
electron concentrations
of 5-1017 Cm-1. The diffusion of zinc from the gas phase into
polished plates each
containing 2-3 seeds took placd at 750C over a 30-min period. The
depth of the p-n
junction was 35 V. The electrical contacts were made of gold which
was sputtered on
plates at 400C. The bar ends were polished and the sides were
roughly worked. The
GaAs diodes were prepared in a similar manner with the following
exceptions: diffusion-
of zinc into GaAs lasted 4 hr at 850C under excess As pressure, and

ABSTRACT: Phenomenological methods were used in an experimental
study of certain
properties of GaAs laser diodes (loss factor, quantum yield,
differential
efficiency, gain). The specimens were prepared by the diffusion of
zinc into n-type
GaAs crystals with electron concentrations of 2 x 1018 cm-3. The
cavities consisted
of silver mirrors sputtered on polished crystalline surfaces
pre-coated with a thin
layer of SiO, and the electrical contacts consisted of sputtered
metal (Au, Ni, In,
SO films and fuse4-in electrodes. T~e measurements were carried
out at 77K and the
pulsed output was recorded by a calibrated silicon photodiode. The
lowest threshold
currents occurred in diodes,which were cleaved on all four sides.
A threshold current
of 25 mamp was attained at the liquid He temperature and at a
density of 75 amp/CM2,
C-w operation was observed from diodes with I thr " 0.5 amp at
4.2K. The results

ABSTRACT: In an investigation of the temporal characteristics of a
GaAs laser the
radiative delay tim:P(T,) was determined as a function of the
injection current.
Ordinary diodes, pr ar d by means of the diffusion process, were
placed in a dewar
at the liquid N temperature. The laser was excited by a current
oscillator with pulse
amplitudes from 4 to 40 amp and a duration of 40 nanosec. Several
diodes were investi
gated at threshold currents from 1.8 to 4 amp. The dependence of T
on injection
current indicates that the value Of T9 approaches 1.8 x 10-9 see.
this corresponds
approximately to the spontaneous radiative lifetimes for electrons
and holes calculatec
theoretically elsewhere (W. P. Dumke, Phys. Rev., 132, 1998, 1963).

increase of Ithr, Tg increases to 0.9 nanosec; this is explained
by the time increase
necessary to achieve population inversion. To eliminate delay due
to spontaneous
emission and to achieve stimulated emission, the diode was pulsed
by currents from an
auxilliary oscillator with amplitudes of 1.5 Ithr and durations of
approximately
200 nanosec. Some 50 nanosec after the onset of the auxilliary
pulse, the diode was
pulsed by a positive current from the master oscillator. The delay
time between the
onset of the injection current from the master oscillator and the
radiation inducedby
it was measured, and at 17 Ithr was reduced to 6 x 10-11 sec. A
further decrease in
T calls for considerably increased injection currents. The
experimental data indicate
tRat GaAs lasers can be used as radiation modulators in the
centimeter band and as
high-speed (10-10-1011 see) optical switches. Orig. art. has: 1

ABSTRACT:
Aleksandr Mikhaylovich Prokhorov is one of the leading Soviet
physicists, a corresponding member of the Academy of Sciences USSR,
and
a winner of the Lenin and Nobel prizes. He is associated with the
development of
quantum radiophysics and belongs to the widely known school of
academicians
L. 1. Mandell shtarn and N. D. Papaleksi. Prokhorov has successfully
combined physical investigations with the development of working
devices
I employing new physical principles and phenomena.
Prokhorov was born on 11 July 1916 in Atherton, Australia. His
fiather
was a polftical refugee who had- migrated to Australia in 1911.
Thefamily
returned to Russia in 1923. In 1939 Prokhorov graduated with honors
frorn
the Physics Department of Leningrad University and entered the
0scilla"ions
Laboratory of the Physics Institute imeni P. N. Lebedev for
posigraduate
work. Prokhorov was in the army from 1941 until 1944. when after
being

wounded for the second time he was rildeased. Prokhorov I s
scientific
activity began in 1939 under the guidance of M. A. Leontovich and
V. V.
Migulin with the study of radiowave propagation along the earth' s
surface.
From this study Prokhorov and Migulin developed an original way to
observe
the ionosphere by means of the radio interference method. In 1944
Prokhorov
investigated the frequency stabilization of tube oscillators in the
Oscillattions
Laboratory.of the Lebedev Physics Institute. His first dissertation
work
was accomplished under the guidance of S. M1 Rytov and was devoted
to the
theory of nonlinear oscillations. Prokhorov, Rytov, and M. Ye.
Zhabotin-
skiy received the Mandell shtam Prize for the development of the
theory of
frequency stabilization.
After defending his dissertation, Prokhorov proceeded with his work
in
radiophysics. In 1948 he began a study of coherent radiation in a
synchrotron.
From this investigation Prokhorov developed a method for
determining the
size of electron bunches and showed experimentally that a
synchrotron
generates coherertt radiation in the centimeter range. He presented
his
'results in the form of a doctoral thesis, which he defended
successfully
in 1951.

Simultanerusly with his work in accelerator physics, Prokhorov,
at -the invitation of ac a~demician D. V. Skobel I tsyn, began
working in the
field of radio spe ctr os copy. Prokhorovl s interest in
radiospectroscopy was
t, encouraged by the fact that well developed methods of
radiolocation and
radioengineering were being employed at that time.' These methods
were
soon to find application in the now field of radiophysics,
principally in the
spectroscopy of the rotational and vibrational spectra of
molecules. Besides
investigating purely spectro~coplc problems, Prokho~ov also studied
the
employment oil t1-e absorption spectra in the uhf range for the
construction
of frequency and time standards. As a result of theoretical
examinations
of ways to raise the stability of molecular frequency and time
standards$
Prokhorov together with N. G. Basov wrote a series of classical
works on
the development of masers, It was at this point that Prokhorov
became
one of the founders of quantum electronics.
Prok:horov and Basov soon offered a new method for obtaining a
system
with negative temperature, the so-called "three levels method, "
which
later became the basic method for developing paramagnetic as well as
optical quantum generators and amplifiers. During the period from
1955 to
1960, Prokhorov concentrated on the development of quantum
paramagnetic
amplifiers in the uhf range, giving special attention to new
crystals' for

ACC NR: AP7011022
paramagnetic amplifiers and to the investigation of their spectra
and relaxa-
tion characteristics. The ruby was investigated in Prokhorov' s
laboratory
and was proposed for use in quantum paramagnetic amplifiers.
Prokhorovt s works in quantum radiophysics were highly regarded. In
1959 Prolshorov and Basov were co-recipients of the Lenin Prim for
developing a
new method for the amplification and generation of electromagnetic
waves.
Prokhorov in 1954 became supervisor of the Oscillations Laboratory,
which under his supervision developed into two new laboratories of
the
Lebedev Physics Institute: the Radioastronomy Laboratory and the
Quantum
Radiophysics Laboratory. A professor at Moscow State University
since
1957, Prokhorov there organized the Laboratory of Radiospe ctr os
copy at
the Scientific Research Institute of Nuclear Physics. One of the
paramagnetic
amDlifiers for 21-cm waves constructed under Prokhorovl s guidance
was
insialled on the 22-m parabolic mirror antenna operating at the
Lebedev
Institute' s Radioastronoxny~ Station at Pushchino (near Serpukhov)
for use
in observing hydrogen emissions from space.
During this period Prokhor ov directed a great deal of attention to
the
search for new crystals for amplifiers and generators in the range
of
millimeter and submillimeter wavelengths.. His greatest attention
was given to
,,C.ard 4/6
ACC NR. A7703-1022
Insers. In 1958, Prokhorov proposed a new type of resonator for
submilli-
meter waves, the so-called open resonator in the form of two parallel
mirror surfaces.
in 1960 Prokhorov was elected a corresponding member of the Ac_Wemy
of Sciences USSR in the Department of General and A plied Physics.
Since
P
then he has concentrated primarily on the study of processes in
cryi~tal
lasers. Prok-horov has investigated and prepared cryi;tals from
fluorite with .
dysprosiurn and other impurities and has succeeded in using solar
radiation
punip fluorite crystals.
A new principle for the operation of quantum irererators b utilizing
y
the two-quantum transitions was developed in 1963 under Prokhorov' s
super-
vision. The construction of multi-photon (in particular two-photon)
transi-
tion lasers is the future of quantum electronics.
In 1964 Prokhorov along with. Basov and Charles Townes was awarded
the Nobel Prize in physics. Prokhorov has since achieved significant
results
in developing continuously operatine lasers for use in
radiocommunications
and technological operations.

'-ACC NR. A71011022
Under ProkhorovI s guiaance investigations have been
proceeding in
solid-state physics, particularly in the area of the
behavior of superhigh
I frequency solid-state plasma. This trend should open up
possibilities for
the construction of new physical devices and a new type of
solid-state
amplifier.
Through the initiative and under the scientific guidance of
Prokhorov,
a special system for obtaining continuous superstrong
magnetic fields with
intensities of the order of hundreds of kilooersteds has
been developed.
This will be the first such installation in the USSR.
A. M. Prokhorov has conducted investigations ranging over
various
fields of physics. Them results of his investigations
ha-.re been published in
more than 160 scientific reports. A member of the
Department of General
and Applied Physics, Prokhorov is also Vice-Presiderit of
the International
Radio Association (URSI) and is Chairman of its Soviet
committee.
Prokhorovt s wor"- have influenced considerably the
development. of
modern physics. His scientific and organizational
activities have greatly
affected the whole comolex of works in quantum radiophysics

ABSTRACT: The distribution of pressiire.in the test press-mold
in dependence on the
temperature of material, specific casting pressure, and mold
design was
investigated. As a test specimen a plate 155 mm long, 20 mm wide
and
2.4- 2.6 mm thick, was used. The pressure was measured in six
plac es,
located over the length of the specimen in a 25-mm distance. The
pressure of the plastic on the walls of the mold was recorded on
a film
of a MPO-2 electromagnetic oscillograph through a 6-channel
tensometer
amplifier. The investigations were carried out on a mechanical
casting
machine of a capacity of 30 - 50 g per cycle, with a variation
in pressure
of from 400 to 1,300 kg/cm2, at a temperature of 170 - 2100C in
intervals

Investigation of-the Effects of Several Technological Factors on

Polystyrene
amounted to 2, 27, 52, 77, 102, 127, 152 mm. Oranulated
transparent polystyrene, ob-
tained by the cut-sbeet methodo was used. The relation between
the maximum pressure
in the mold (P ), the specific pressure (P.) and the temperature
of the heating cylinder
obtained &m the curves-by the method of least squares, looks as
foolows:
P
Pm a + 0.00626 to

where a is the coefficient dependent on the thicknega of the
manufactured object. The
quantity a depends on the perimeter of the plate, according to
the equation: a -
~ -1.016 + 0.90056 rl , where n is the perimeter. The
investigation of the character
of pressure variation in the mold under different casting
conditions showed that the
relative pressure drop P/Pm over the length of the manufactured
object is the higher,
the lower the temperature of the material to be pressed and the
thinner the specimen.
The relations obtained are expressed in the form of the
empirical formula:
- P - 0.72 . e-0.134K + 0.28e -3,98K

where K X Is the variable length of the manufactured object.

Abstract: In 12 healthy and 32 sick horses the amount of
general
N was determined, of protein N and of globulins, of
the residual N, of the amunts of urea (I) and of
creatinine in the gastric juice (W) before the feed-
ing of the aninals. Also determined were for the
blood serum the amount of protein, the protein coef-
ficient, residual N, I and creatinine before and after
