SELF-MODE-LOCKING OF CW SOLID-STATE LASER S USING A NONLINEAR ANTIRESONANCE RING

A study was made of the self-mode-locking of cw solid-state lasers acc omplished by a modulator in the form of an anti-resonance ring contain ing a bulk self-phase-modulation element. The modulator had a high ini tial transmission and could effectively distinguish between radiation fluctuations. The characteristics of a self-consistent ultrashort puls e calculated from an approximate analytical solution of the problem of cw generation were investigated as a function of the modulator parame ters. The laser system parameters were found to conform with the regio ns of effective self-mode-locking that were established by numerical s imulation of the generation of stable trains of ultrashort pulses from the noise radiation of the continuously pumped active medium.
