Abstract

Abstract

This paper describes what is thought to be the first generation of a continuous wave deep ultraviolet laser at 275 nm by efficient frequency doubling of a blue-diode-pumped Pr:YLF laser at 550 nm. By employing a novel fast-axis collimated blue semiconductor laser as the pump source, combined with a folded cavity and innovation coating technology, and utilizing a Brewster-cut BBO crystal for intracavity frequency doubling, TEM₀₀ mode deep UV laser radiation at 275 nm with an output power of 351 mW is obtained. This marks the first report of achieving 275 nm laser generation based on Pr:LiYF₄ to date.
