INVESTIGATION OF A CR4+YAG PASSIVE Q-SWITCH IN CW PUMPED ND-YAG LASERS

摘要

This work describes the experimental results obtained on the Cr4+:YAG crystal used as a passive Q-switch in Nd,YAG lasers, In addition, the combination of a Cr4+:YAG passive Q-switch with an acousto-optical Q-switch operating simultaneously in one cavity was investigated, More than 180 W average output in the passive Q-switched mode was obtained with the Cr4+:YAG crystal, The pulse-to-pulse stability was better than 1%. A mode selection occurred when the laser system operated near threshold, (C) 1997 Elsevier Science Ltd. [References: 17]
