Abstract

By using Cr4+:YAG as a saturable absorber, ahigh energy and high stability Q-switched pulse with a single pulse energy >85 mJ,pulse-width of 40 ns and energy fluctuation of 0.4% was obtained in an unstable resonatorNd:YAG laser with ananti-resonant ring (ARR) structure. The experiments on plane-convex unstable resonator andplane-plane critical resonator were also tested for comparison and the results wereanalyzed.
