Popis:	Relaxation processes are allowed for in an analysis of the influence of a gaseous nonlinear absorber on oscillations of a single-mode He?Ne/CH4 laser when its resonator length is varied periodically at a frequency ?. Investigations are made of the frequency and amplitude modulation parameters as a function of ? and of the tuning of the average oscillation frequency within the methane line. It is shown, in particular, that the dependence of the radiation frequency deviation on ? changes substantially when the average laser frequency is detuned from the center of the methane transition by a value appreciably greater than its homogeneous width.
