Abstract

A CPM, Nd:YAP (and YAG) pulsed laser with an ARR-convex unstable resonator is designed. It combines the advantages of both CPM configuration for narrow pulsewidth and unstable resonator for high output energy. This ideal fundamental wave source delivers a single pulse train with energy several tens of mJ, pulsewidth 10 Psec, and energy fluctuation < 2%. Using intracavity frequency doubling and choosing KTP, BBO and LBO as SH generator, a powerful and efficient SHG at green is generated with SH energy > 48 mJ, power density > 5 GW/cm² and conversion efficiency as high as 50 - 70%. The theoretical analysis tallies with the experimental results.
