Paper Abstract

Bulk laser damage in CsLiB6O10 was measured using a single-shot Q-switched Nd:YAG laser in a transverse and longitudinal single model. The bulk laser damage thresholds of CLBO, with laser irradiation direction (parallel) < 001 > and polarization (parallel) < 001 >, were determined to be 29 GW/cm2 at 1.064 micrometers , and 6.4 GW/cm2 at 0.266 micrometers . The value at 1.064 micrometers is higher than that of fused quartz, (beta) - BaB2O4 and KH2PO4. The morphology of bulk damage in CLBO crystal was also observed. THe damage pattern suggests that the < 001 > direction is mechanically weak, which is consistent with the result of the mechanical strength tests.
