Paper Abstract

Numerical simulation indicates that the mechanism of self-pulsing instabilities in fast-flow laser with unstable resonator is connected in many cases with teh rise of relaxation oscillations. Spatial structures, frequencies and increments of the perturbation modes have been calculated in linear approximation. Effects of interaction of relaxation oscillations and flow self-oscillations such as pulling and locking of frequencies were observed. The transformation of relaxation self-oscillations into different saturated regimes of lasing was also investigated. The regimes may be of practical interest due to high pulse repitition rate (up to 104 Hz).
