Abstract:
On the basis of spatio-temporal numerical model the non-stationary manifestation conditions in frequency-modulated cw laser beam propagating in resonance conditions are investigated. Generation of subharmonic and optical frequency division are observed and analyzed in conditions of cw laser beam resonance self–action.

Key words:
resonance self-action, laser beam propagation, non-stationary, medium response, frequency modulation, period doubling, frequency division.
