Abstract
A conductively cooled pump head with a triangular-prism laser rod is proposed and discussed. A pump absorption efficiency of ~80% and better pump intensity distribution were expected from the results of simulations. An output energy of 95 mJ and an optical-to-optical conversion efficiency of 10% were obtained at a pulse repetition frequency of 5 Hz in normal-mode operation. Using a fused-silica acousto-optic Q-switch, the laser produced an output energy of 21 mJ in a single Q-switched pulse. No parasitic oscillation occurred even when the laser rod with polished lateral surfaces was used in Q-switched operations.
