By using GaAs as an output coupler as well as a saturable absorber, passive Q-switching of an arc-lamp pumped Nd:YAG laser has been demonstrated. The shortest pulse duration obtained was 77.6 ns, corresponding to a pulse energy of 34 ?J. The laser average output power was 2.1 Wwith a power density in GaAs at 1.5x 103 Wcm-2 No optical damage to GaAs was observed without any active cooling.
