摘要：

We report, for the first time, efficient intracavity second-harmonic generation (SHG) at 1.06 mum in a non-linear optical crystal, BiB3O6 (BIBO), at a type-I phase-matching direction of (theta, phi) = (168.9 degrees, 90 degrees), performed with a LD end-pumped cw Nd:YVO4 laser. A cw SHG output power of 364 mW has been obtained using a 1.9-mm - thick BIBO crystal. The optical conversion efficiency was 12.2%. and the corresponding effective intracavity SHG efficiency was determined to be 32.4%. It was found that the intracavity SHG efficiency is greater than that obtained with a type-II phase-matching KTiOPO4 (KTP) crystal with a thickness of 3 mm. The effective non-linear optical coefficient (d(eff)) ratio of BIBO to that of KTP, determined experimentally, is 1.23 : 1.
