TITLE: Theory of laser Emission
SOURCE: AN SSSR. DokIpAy*, v. 155, no. 6, 1964, 1298-IN1
TOPIC TAGS: laser, stirmil ted light emission, radiation transfer, continuous laserp
pulBe laser, solid state laser
ABSTRACT: The authors use the transfer equations for generation of light in lasers
with a solid rod having parallel mirrored ends. In these equations, they separate
the absorption coefficient into two parts., one connected vith stirmilated emissionp
the other with the rent of the processes. The fixot part is proportional to the
overpopulation, I.e.,to the excess of the number of atoms in the upper state over
that of tha lower, per unit volume. The equations are solved for both the
stationary case (continuous laser) and the discontinuous case (raisa operation).
For the case of a negligibly maLl reflection co-efficientp the solution gives the
passage of photons through an averpopulated medium. Orige art. has: 15 formulas.

ABSTRACT: The passive-witched ruby laser was investigated by the authors earl-ter

neglected pumping and relaxation processes transpiring during the pulse radiation.
The present article reports some results obtained on a cow4mter which clarify the
effect of the relaxation between the levels of the viodulator substance (phthalo-
cyanine) and the tiae characteristics of radiation'. The calculation shown

ABSTRACT: A scheme is proposed for a simple gating device which contains a 450 pola-
rization rotator, a 450 quartz rotator, and a polarizer. A plane polarized light beam
passes through the quartz rotator, the polarizer and the active substance where under
the applied field the polarization of the beam is restored to its initial condition.
The reflected 1-ight is polarized identically as the beam leaving the gate is rotated
45(l more by the rotator, and is either carried away or is absorbed by the polarizer.
Requirements for an optical gate are maximum decoupling, minimum loss, minimum distor-
tion, minimum reflection, lightweight, and small size. The Faraday effect was studied
with special terbium-aluminum garnet. Among diamagnetic glasses studied were samples

rich in lead oxide. The highest @erdet constant is obtained with PbO'CeO-IBr0j,
P20r,_, ank aluminum silicate glass,*Idoped with terbium. The Faraday effect is directly
dependent on the ceric oxide content of the glass. The Verdet constant was measured
for the various samples of various thickness and was found to fall off in moving from
green to red light. A polarization rotator was made of two 9.5 mm pieces of ThAl
Lgarnet glued together, which at X=0.63 ij, required a field of 4800 oe to rotate the
T @Ight450. The overall length of the gate is 13 cm. Losses are 2.2 db looking in
and decoupling is equal to 28.5 db. Methods of improving the design are suggested,
especially by using a single crystal. The design may be used in an optical circulat-

ABSTRACT: The authors show that the theoretical advantages of hologra hy@ethods
for obtaining three-dimensional pictures, namely high and large dynamic brightness
range, are offset in practice by the presence of noise, which comes into play during.
the reconstruction of the image in a maimer entirely different from ordinary photo-
graphy. The randomly disposed emulsion grains, which are separated by appreciable
distances (compared with the wavelen6,th cause the interference pattern registered
on the hoiogram to have discontinuities that scatter the coherent li@-,ht transmitted
throu!;h such a hologram. The spatial distribution of the scattered radiation obeys
statistical laws that are characteristic of shot noise. A formula is presented for
the ratio of the useful cignal power to the power of the background produced by
scattering, from these inhomo(reneities. 'Me derivation of this formuia if; basea an

the experiments show that the jraininess of the emulsion influences not only the
resolving power of the imaj;e, but also, more importantly, the level of the background
that distorts the brightness distribution in the image. The authors thank I. R.

ABSTRACT: Methods of foming three-dimensional images with coherent light are discus-
sed. It is shown that these methods will produce high quality reproduction of images
since the resolution at the image is limited only by diffraction at the aperture and
the size of the hologram or interferogram is equal to the size of the aperture. Some
experimental results are described. (Abstracter's note: This is essentially the en-
