Non-collinear phase-matched 355 nm UV generation in a prism-coupled CsLiB6O10 crystal

A walk-off compensated prism-coupled device based on non-collinear phase-matching in CsLiB6O10 (CLBO) generates 2.55 W output of 355 nm UV light with 52.8% conversion efficiency from the geometric mean of input infrared and green powers.
