ABSTRACT: The authors obtain equations for the sections of the wave surfaces by the
MYMWtrY Planes for rhOMbiC.. hexagoM1j, tetragona,, add cubic crystals in a parametric
form., and for arbitrary crystals in an impucit form,' and investigate the singular
points of these sections. All the calculations are based on the fact that the sec-
tions of purely transverse vaves by the symmetry'planes are ellipseso-and the equap.-
tions for *the di:,Yerent symmitries are obtained by substituting the proper moduli of
elasticity and other constants. The investigation of the sir4gular points, which has
not been carried out by anyone before, is based on eliminating the angle variable
from the parametric equations by =man of a coordinate transformation. It is shownp.
In aaeamez* vith earlier results by one of the authors (Fedorovj, Teoriya upurgM

TITLE: Electromagnetic field of a plane-parralet layer in conditions of self-excitation
PERIODICAL; Akademiya nauk Belaruskay SSR. Doklady, v. 6. no. 5, 1962, 297-300
TEXT: This paper is a continuation of: A. M. G(,ncharenko and B. A. Sotskiy, DAN USSR, 6, no 4, 1962,
A system of equations is written for the normal and parellel components of electromagnetic fields, propaga-
ting inside and outside an active plane-parallel layer. These equations contain the refraction angle and di--
electric constants. Expressions are given for the electric and magnetic fields inside the layer and also for the
time and phase averaged energy density and Poynting vector. For the lait two a definite dependence of the
dielectric constant on the radiation density is assumed. An agreement is claimed between numerical values
characterizing the system of rings actually observed on a screen (T. H. Maiman and otheirs, Phys. Rev 123.
1151, 1961) and those predicted by the present paper. There is one figure.

T;TLE: Diffraction of partially coherent light
SOURCE: AN BSSR. Doklady,*, v. 8, no- 7, 1964, 438-44o
TOPIC TAGS: physical optics, dielectric resonator, light dIffraction, partlally~
coherent light
ABSTRACT: An attempt has previously been made to calculate the diffraction of
partially coherent light at a narrow slit, given an exponentially decreasing co-
herence function. Since the implicit assumption that the latter satisfies the
wave equation is not satisfied, the results obtained are doubtful. in tile presents
paper, the calculation is made for a coherence function of the form (sin X)LX
where cc is the coherence interval. The diffracted intensity found does rlot giffer,;
greatly from that for monochromatic light when Zalct Is small, where 2a Is the
width
_of the slit. When this ratio Is large, the divergence of the-radiation is
I.A /211ct, independent of the slit width, as confirmed by experiment. For dielectri * C'
resonators this angle will be several tens of minutes. It Is not known how well i
he coherence function fits the case of a dielectric resonator; however, It satls-'~

Of electromagnotiia waves In a plane-parallel slab under conditions of total refloc-'
tion. The approach is solution of the Maxwell equations with the appropriate boun-
'dary conditions; an analogous problem was solved earlier by two of the authors (A.
M.Goncharanko and B.A.Sotskiy,DAN BSSR,6,223,297,1962), and the expressions for'the.
condition necessary for self-excitation are taken from thaw papexa, By separation of
Ithe real and imaginary parts and introduction of the Presnel reflection coakficled%,
the conditions for self-excitatica in a plane-parallel slab are derived In
the case of total reflection from both facas. Analysis ct the expressions shown thst?f
~
:self-excitation is impossible if the imaginary component of the dielectric constant'
.(i.e.,the negative absorption) Is smaller than zero, that is, in the region of Un-:
ear optics; however, the energy density in the layer may build up to the point vbm,
in the limit the medium becomes transparent and self-excitation becomms possible
(but, of course, no radiation can be extracted without violating the condition for
total reflection). The equations are also extended to the case of a slab with total:
reflection only at one face; in this case self-excitation (laser oscillation) be-
!comes possible in the region of linear optics. The condition for generation Is af-
fected primarily by the value of the ordinary Presnel reflection coafficlent. "ne

layers of equal thickness of uniaxial crystals with an arbitrarily
oriented optical axis. This represents the simplest'model of an
actual Crystal which has a nonuniformity of the refractive index
