摘要
本文提出了一种能较大程度优化大口径晶体面形的夹持方案，同时分析对比了优化方案与常规方案下重力作用对 KDP晶体面形和三倍频转换效率的影响。研究结果表明：优化方案能极大的改善重力对 KDP晶体面形的影响；同时当基频光光强为 5.5 GW/cm2时，优化方案较之三种常规方案的三倍频转换效率分别提高了 6.2%、9.5%和 6.5%。
Abstract
A new kind of clamping scheme presented could make the crystal surface optimized, and numerical calculation is used to analyze the influence of crystal gravity sag on KDP surface and conversion efficiency by adopting the optimized scheme as well as routine schemes. The results show that optimized clamping scheme could improve the effects of KDP crystal gravity obviously. When the intensity of fundamental light is 5.5 GW/cm2, compared with routine schemes, the conversion efficiencies by adopting the optimized scheme increase 6.2%, 9.5% and 6.5%, respectively.
