本文报道了1.064 μ mNd：YAG激光器的连续准相位匹配腔内倍频。周期性极化的LiNbO 3晶体长5 mm，厚0.2 mm，采用布鲁斯特角切割。当位于腔内时，其有效非线性系数d33为4.5pm/V，估计的单程损耗小于10%。观测到的温度带宽为1.5K，与理论值相比较，表明晶体的整个长度都对倍频过程有贡献。
We report on CW quasi-phase-matched intracavity frequency doubling of a 1.064 μm Nd:YAG laser. The 5 mm long and 0.2 mm thick crystal of periodically poled LiNbO3was Brewster angle cut. When located intracavity, it presented an effective nonlinear coefficient d33of 4.5 pm/V and an estimated loss per pass less than 10%. The observed temperature bandwidth of ∼ 5 K compares favourably with the theoretical value and indicates that the whole length of the crystal was contributing to the frequency doubling process.
