title: High-power intracavity second-harmonic generation of 1.34 microm in BiB3O6 crystal.
abstract: The phase-matching curve and effective nonlinear optical coefficient distribution for the second-harmonic generation of 1342 nm in BiB3O6 crystal were calculated. High-power intracavity second-harmonic generation of 1.34 microm in BiB3O6 crystals, at a type-I phase-matching direction of (theta, ø)=(9.07 degrees , 0 degrees ), was performed with a LD-end-pumped Nd:YVO4 laser. The maximum continuous-wave (CW) and quasi-CW output powers at 671 nm were obtained to be 1.22 W and 4.38 W, with the corresponding optical conversion efficiency of 4.9% and 9.5%, respectively.
