一种新型晶体GdCa4O(BO3)3的非线性光学性能研究
Nonlinear Optical Properties of a New Crystal GdCa4O(BO3)3
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5 mm长的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.
