  • 测量了BIBO晶体的主轴折射率.对BIBO晶体在整个空间内的倍频性质进行了系统讨论.当基频 光为Nd:YAG激光时(λ=1064nm),发现最大的有效非线性光学系数位于(168.9°,90°) 的Ⅰ类相位匹配方向上.测量了BIBO晶体的容限角、容限温度、光损伤阈值,以及1064nm的 腔外、腔内倍频性质.实验中,最大腔外倍频转换效率达到68%,腔内倍频输出达到1.06W.
    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.
