Efficient all solid-state UV source for satellite-based lidar applications

Armstrong, Darrell J.; Smith, A.V.

A UV generation system consisting of a quasi-monolithic nonplanar-ring-oscillator image-rotating OPO, called the RISTRA OPO, is presented. High beam quality and the absence of mirror adjustments due to the monolithic design make this OPO well-suited for demanding applications such as satellite deployment. Initial tests of self seeding using low-quality flattop beams with poor spatial overlap between the OPO's cavity mode and the spatial mode of the injected signal pulsed showed pump depletion of 63%.
