Paper Abstract

We have developed GdxY1-xCa4O(BO3)3 (GdYCOB) crystal in order to control birefringence. As a result, GdYCOB is noncritically phase matchable for third- harmonic generation of a 1064 nm light by type-I mixing (1064 + 532 yields 355 nm). However, during high-power operation, degradation of output power and distortion of beam pattern occurred due to photo-induced damages and thermal dephasing. In this paper, we report on nonlinear optical properties and improved the performance of GdYCOB by suppression of photo- induced damages and thermal dephasing.
