Paper Abstract

Optically-pumped semiconductor lasers provide efficient laser sources in the ultraviolet by intra-cavity nonlinear frequency tripling. A laser combining InGaAs gain media with LBO nonlinear crystals produces hundreds of mW CW at 355 nm. A compact package that combines thermal and opto-mechanical stability is the key to making this laser robust and manufacturable. A temperature controlled, monolithic aluminum base supports opto-mechanical mounts made from low expansion alloys and ceramics to create a resonator that can withstand substantial environmental excursions.
