| 摘 要： | 计算和测量了ＧＣＯＢ晶体的相位匹配曲线，理论计算与实验测量结果符合的很好。用电光调Ｑ的Ｎｄ：ＹＡＧ激光器对５ｍｍ和匠ＧＣＯＢ晶体进行了倍频研究，得到了２６．７％的倍频转换效率。并与同样长度的ＢＢＯ晶体进行比较，得出了ＧＣＯＢ晶体的有效非线性光学系数接近ＢＢＯ晶体的有效非线性光学系数的结论。

| Abstract: | The phase-matching curve of GCOB crystal was calculated and experimentally measured. The measured data of phase-matching angle are well fit to the calculated curve. The second-harmonic generation conversion efficiency of a Q-switched Nd:YAG laser with a GCOB crystal of 5 mm in length is about 26.7%. Comparing its conversion efficiency with that of the same length BBO crystal, the effective nonlinear coefficient is estimated to be close to that of BBO crystal. |
