本文描述了利用光学共振增强KDP中光学二次谐波产生和混频的实验和理论结果。同时考虑了谐波共振和基波共振。对于低损耗的谐振器，可以进行大幅度的增强。使用含有1.23 cm KDP的平凹谐振腔，作者实现了每通损耗< 4%。这使得谐振器内部的谐波功率提高了~ 500倍，谐振器外部的谐波功率提高了~ 10倍。共振时，观察到~ 5的基本增强。该理论包括了双折射效应。这导致产生的谐波功率到谐波谐振器的横向模式的耦合系数。实验结果与理论基本一致。
Experimental and theoretical results are described on the enhancement of optical second harmonic generation (SHG) and mixing in KDP by the use of optical resonance. Both resonance of the harmonic and of the fundamental are considered. Large enhancements are possible for resonators with low loss. Using a planoconcave harmonic resonator containing 1.23 cm of KDP, the authors achieved a loss < 4 percent per pass. This resulted in an enhancement of ∼ 500 times the harmonic power internal to the resonator and ∼ 10 times external to the resonator. When resonating, the fundamental enhancements of ∼ 5 were observed. The theory includes the effect of double refraction. This results in a coupling coefficient of the generated harmonic power to the transverse modes of the harmonic resonator. The experimental results are in substantial agreement with the theory.
