Sum frequency mixing of copper vapor laser output in KDP and beta -BBO

Abstract
Generation at 271 nm by frequency summing the two copper vapor laser (CVL) output wavelengths (at 511 and 578 nm) in β-BBO and KDP is reported. A maximum sum frequency output of 100 mW was obtained for 6.8 W total pump power from a CVL operating with a fully unstable (M =16) confocal cavity.3 page(s
