Paper Abstract

Results of consideration of nonlinear dynamics and switching regimes in a solid state laser with a saturable absorber, which take into account spectral properties of both an active medium and saturable absorber with different resonant frequencies, give us multi-stability of their steady states and coexistence of two regular regimes with sequences of nanosecond sinusoidal pulses or picosecond high intensity pulses both with constant in time intensity regime in dependence on the beginning conditions. Switching regimes between coexisting steady states are demonstrated. Another model is proposed for consideration of the polarization of light in a isotropic cavity with crystal active medium and saturable absorber. Steady states both with two directions of linear polarization as result of self induced anisotropy effects are described.
