TEXT: A double resonator molecule generator is investigated. It is sh..~
that a molecular cultrent polarized by a monochromatic emission excites
a Al.
monochromatic oscillation in a resonator on which it is incident* The
frequency of this oscillation coincides with the frequency of the
polarized
emission. A change in the eigenfrequency of the resonator affects only
the amplitude and phase of the excited oscillation, not its frequency.
The emission-with frequencies different from that of the polarized field
is incoherent. Therefore it is not necessary to take the effect of
coherence into account while calculating the noise produced in quantum
generators and amplifiers by spontaneous emission. If the polarized
emission is not monochromatic the response of the resonator is also not:,
monochromatic for small intensities. The spectrum of the response affects

TEXT: The quantum generator shown in the figure is described. This
operates on the principle of A. Javan (Phys. Rev. Lett., 3, 87,
10,59, 6,
106, 1961). Thie discharge in the ias mixture is excited by-a 10-Mc
generator by -.-.-ay of external electrodes. Interference mirrors
with a high
coefficient of reflection are used. They consist of 13 quarter:-wave
ZnS
films and cryolite. The mirror backings were optical fused quartz
with a
transmi*5'sion factor of ab8ut 1 % for 11,530 9ft waves. Power ~nd
angular
deDendence of the 11,530 h emission were measured. The beam
divergence was
about one. angular minute and the power about 8.2 m-..-. The latter
remained

partial
pressure.ratios of 1:10-1:4 but decreased when the neon partial
pressure Tas
further increased. There is I figure.

agree well with the calculated data. The power yield of the ND3
maser is approximately one-hundredth that of the maser, but the

ABSTRACT: The Physics Institute AN SSSR has investigated the relation-
ship between the output of the neon-helium laser and its various
parameters, i.e., the dAameter and form 'of discharee~tubesii discharge
duration, mixture pressurl,,pumping power, and transmission coefficient
of the mirrors with metil c and dieleceric coatini ior the most in-
tensive spectrum line (Ne3S2-3P4,X - 3.39 V). GrapWs!of output power
Cin millivolts across the measuring photoconductive cell) as a func-
tion of pumping power were plotted for various pressures in the dis-
charge-tube. The discharge.length was 0.9 m. Maximum output power
was obtained with a pumping power of 1001w and a pressure of roughly
1-2 mm HS. The diameter.-of';the generatedtlight spot was equal to that

the tube from 0.3 to 6 mm ft did not disturb the stable operation of
the generator. Generation cutoff occurred at a pressure of about
&,mm Rg. The optimum diameter of the tube was found to be 12 mm at
3.39 v. Output power depended only slightly on the change of
pressure within the range 0.9-1.4 mm H& and increased linearly with
the length of the discharge. Output power oscillations were de'Eicted
during nonalignment of the mirrors. Some 100 maxima were observed
during shifts of the mirror i10. The relationship between output
power and mirror transmigsion coefficient was investigated for co-
efficients of 2, 30, and 50%. The highes.t power was observed at 30Z.,

experimental study of recombination emission in germanium, silicqn,
and
gallium arsenide at various temperatures employs a ruby laser (6934
A) to ob-
tain high excitation levels. Samples of n-type germanium with a
resistivity of
40 ohm-cm and a diffusion length of 1. 5 mm in the shape of a
')Yeierstrass
sphere" 8 mm in diameter were excited by light pulses with a
duration of
200psec and a density of 106w/cm~. Aspectrometer with a 1-ead sulfide
indicator (100 tL see time constant) was used to analyze the
recombination emis-
sion pulses. The signal was amplified by a broadband amplifier and
registered
by a dual-beam oscillograph. Laser output was monitored by a
photomultiplier.

ABSTRAM An optical amplifying By3t6M is presented, consisting of
a Q-switching ruby laser driving a unidirectional amplifier laser
The Q-switch of the signal source was provided to determine properly
the shape. length, power, and time reference of the driving pulse,
The unidirectional feature of the driven laser, achieved by a third
mirror taking the return path outside the ruby rod, renders the
threshold adjustment of the system loss critical and makes it
easier
to 'reach stable gain. Furthermore, the unidirectional system allows

for the employment of several amplifying lasers in series without
Interstage isolators. In the experiment, the overall power gain was
measured as a function of alngle-pass gain. An overall gain in the
vicinity of 10 was recorded against a single-pass gain of 6 and the
ref lection coef f itient of the semitransparent mirror v= etpal to

In order to aeasure the sensitivity of the amplifier, Lhe photomul-
tiplier va3 placed as far from it as possible to reduce luminescence
effects and a fl&sh lamp quenching device was used to eliminate the
pump background. The measurements showed that the 3yaten is &ensl-

laser amplifier. The block disgraMLof a setup.used for the
measurement of the am-
plifier response is shown in Fig. 1 of the Enclosure. A
neodymium-glass laser with~
Q-switching was used as an exciter. The laser output was transmitted
through the :
Itheodolite T, where it was focused and subpequently converged on an
object with var..'
liable transparency. After passage, through #r_-theodolite the
angular divergence of the
ibeam was smaller than the angular diffraction at the input and
output apertures of
Ithe amplifier. The beam from the theodolite was attenuated by
neutral filters which
were precalibrated to the laser wavelength (1.06 mv). After passage
through an
object, one-half of the beam was separated by a 50%.mirror and
photographed. The
!
other half was *passed through a neodymium-glass amplifier and was
also photographed~~

ABSTRACT: A theoretical analysis is conducted of the mode of'operation
of an injection laser consisting of an array of p-n junctions In which
oscillations are synchronized in order to obtain larger power output
and better directionality of laser emission. An slectrodynamic model

quency In which there are only the lowest order standing waves E.,
and Hoc is used in deriving & formula for the internal coupling of the
junction due to the penetration of the fields An eipresslon Is also

developed by N. G. Basov at &I uhich is described in a paper yet to be
publ.ished. External diffraction coupling of p-n junctious is obtained
by making a hole In the face of the semiconductor and using an
external
mirror. The criteria for stability of the synchronized mode of oper-
tion are obtained by analyzing the oscillation equations of a system
similar to that of two interacting lasers. Numerical estimates for a
typical p-n junction show that synchronization of oscillations is more
favorable In the case of external coupling* Orig. art. hass 5 form-
