Paper Abstract

High-power solid-state UV lasers are in high demand because of the convenient operation procedure. An effective technique for UV generation is cascaded sum-frequency generation pumped by the output of near-IR solid state lasers. The major challenge to such a UV laser seems to depend on the ability and reliability of the nonlinear optical (NLO) crystals that employed for frequency up conversion. The recent development of borate materials such as CsLiB6O10(CLBO) and (open square)-BaB2O4(BBO) have permitted an improved UV generation. In this work, we have investigated the bulk laser damage and the light scatter from bulk defects in CLBO and BBO crystals.
