Abstract
Advanced resonator designs for Ho3+:YAG lasers and ZGP OPOs are presented. A segmented Ho3+:YAG crystal for power scaling was investigated. An improved power performance could not be shown up to 60W of output power, which is attributed to the low overall crystal temperature. Exploiting the Porro prism resonator concept for the first time, a 200-times increased alignment tolerance compared to a corresponding mirror resonator was achieved. The performance of a ZGP OPO could be improved by a negative lens in the resonator, which significantly enhances the beam quality.
