The influence of pulsed lazer radiation which is selectively absorbed by a buffer agent on a gas mixture combustion in a CSTR was studied in non – linear approximation. The relation between the resulting amplitude of system oscillations with the frequency and amplitude of an external action was found. Resonance phenomena were detected on a natural frequency and its multiple frequencies. It was shown, that in the vicinity of resonance at natural frequency the amplitude – frequency characteristic may be crisis – free or a hysteresis one, and the apmlitude of oscillations was proportional to the cube root of external action amplitude. Results of analytical consideration were corroborated by nymerical solution of the non – linear problem.
