Abstract
We investigated bulk laser damage in CsLiB6O10 (CLBO) and its relation to c rystal structure. The damage thresholds of CLBO, with the laser irradiation direction \\ (001) and polarization \\ (100), were determined to be 29 GW/ cm(2) at 1.064 mu m, and 6.4 GW/cm(2) at 0.266 mu m, using a single-shot Q- switched Nd:YAG laser in a transverse and a longitudinal single mode, respe ctively. It was also found that the laser damage thresholds strongly depend on the direction of laser irradiation and polarization. The threshold and morphology with crystallographically oriented cracks suggest that the (001) direction is structurally weak, which is consistent with the result of the mechanical strength tests.
