A Cellular Automaton Model of a Laser with Saturable Absorber Reproducing Laser Passive Q-switching

Abstract:

In this paper, we present a cellular automata model for a two-level laser which includes a saturable absorber. We show that the model reproduces laser passive Q-switching, a behavior in which intense short pulses of laser radiation are produced. Depending on the concentration of the absorbent, the automaton model qualitatively reproduces two operating states of the laser: a stable state and another oscillatory or pulsed state.
