Coexistence of Dynamic Regimes in Laser with a Saturable Absorber
L. A. Kotomtseva and S.G. Rusov

Results of dynamics consideration in a solid state microlaser with a saturable absorber with arbitrary resonant frequencies of the transitions in active medium, absorber and the cavity are proposed. There are due to simultaneous action of absorptive and dispersive nonlinearities up to 5 steady states with constant in time intensity at different frequencies. Regimes with constant, sinusoidal in time nanosecond oscillations of intensity and sequences of regular picosecond pulses may be observed in one laser at the same parameters.
Key words: nonlinear dynamics, solid state laser,saturable absorber
