| Abstract: | For BiB3O6(BIBO) crystals the refractive index on the main optical axis was measured. A systematic research was performed on the frequency-doubling property of the BIBO crystal. When the fundamental light was supplied by a Nd:YAG laser (λ=1064nm), the largest effective nonlinear optical coefficient was found in th e Type-Ⅰ phase-matching direction (168.9°, 90°). We measured the angular acce ptance, temperature acceptance, laser damage threshold, and the ultra-cavity as well as the intro-cavity frequency-doubling characteristics of the BIBO crystal. In our experiments, the largest ultra-cavity frequency-doubling conversion effi ciency was 68%, and the intro-cavity frequency doubling output power reached 1.0 6W. |
