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.
