TITLEt Averaged laser equations and their stationary solutions

no. 3, 1964, 963-969

ABSTRACT: The difficulties involved in solving the rigorous non-
linear laser equations are listed, and it is shown that some of the
solutions obtained are incorrect. Some laser theory aspects con-
nected with the influence of the nonlinear medium on the field struc-

ture are considered, and.it is shown that the initial equations can
be averaged under some general assump~Aons and reduced to a lower
order system for slow time-varying quantities. in particular,
averaged eq6ations are deriyed for the electromagnetic field in a
two-level ac'tive medium without expansion in the eiganfunctions of
the unperturbed system, and are solved for stationary nonlinear os-
cillations in a plane layei with arbitrarily reflecting boundaries,
which can be regarded as a one-dimensional laser model. The fre-
quency spectrum of such oscillations and the corresponding spatial
distributions of the field phase and amplitude are obtained. The
components obtained determine the finite number of possible non-
linear oscillations (modes) whose frequencies differ from the natural
frequencies of the unperturbed system, and whose amplitudes and
phases depend on the coordinates. it is emphasized that the super-
position of these modes is not the solution of the problem and that
the question oi existence of other stationary processes (auch as os-
cillations with periodically varying amplitudes) still remains open.

1.a frequency-modulated wave, propagating in a system having an arbitrary dispersion
characteristic, is described by a first-orxier nonlinear partial differential
equation. A Riemann Integral Is the solution of this equation In a aingle-variablo
case. The variation of the wave amplitude depends on the shape of the frequency
envelops. It Is found that, under certain conditions, the dispersion results In

ifrequency changes. A certain similarity between the propagation of group fronts

made that Wer transients involve only one fundamental cavity mode are not al-

author then proceeds to obtain, within the framework of the model of a two-mode
laser cavity, a bufficiently complete picture of both the ataticnary and nonsta-
