ABSTRACT:
A Q-switched solid state laser provided with a laser medium, a pump source for generating pumping light used to pump the laser medium, a pair of laser resonance mirrors respectively placed at both sides of the laser medium and a Q-switching acousto-optical element intervening between the pair of laser resonance mirrors for controlling Q-switching oscillation by abruptly changing a loss of resonant laser light passing therethrough. Further, the Q-switching acousto-optical element satisfies a predetermined condition .vertline.Ms.vertline..gtoreq.1.times.10.sup.-12 S.sup.3 /g..degree.C. where Ms denotes a parameter defined as Ms=M/(ds/dt) by letting (ds/dt) designate a thermal change in optical path of the Q-switching acousto-optical element and also letting M represent a performance index of an acousto-optical material of the acousto-optical element. Thereby, the Q-switched solid state laser excels in what is called a "beam pointing stability" and "pulse-to-pulse stability".
