| Abstract: | We report the use of bismuth borate for efficient intracavity frequency doubling of an optically pumped semiconductor disk laser. An output power of 220 mW at 529 nm at room temperature has been demonstrated, corresponding to 52% conversion efficiency with respect to the fundamental power. The results are compared to frequency doubling with a potassium titanyl phosphate nonlinear crystal. PACS 42.55.Px; 42.70.Mp; 42.72.Bj |
