On the basis of spatio-temporal numerical model the dynamics of frequency-modulated cw laser beam propagating in resonance conditions is investigated. At modulation periods comparable with the atomic relaxation times the time and frequency dependence of the output intensity exhibits the manifestations of delayed medium response and resonance self-action. Time dependence of output intensity and spot size are measurement parameters. On the basis of phase portraits and power spectrum analysis we found a different dynamical regimes.
