In this paper we have investigated the effect of pump induced bleaching of the saturable absorber in a passively Q-switched microchip laser on the laser parameters such as pulse width and pulse energy. The induced bleaching will be increased by moving the focusing position away from the surface of absorber crystal. The minimum effect of bleaching will be achieved by optimizing the focus position while the pumping volume is nearly fixed in the gain crystal. We report decreasing of pulse width by 150ps and increasing of pulse energy by 9μj in this experiment.
Keywords: Induced bleaching of saturable absorber, Passively Q-switched microchip laser, Pulse width, Pulse energy
