Abstract

A multi-pass side-pumping scheme for solar pumped Nd:YAG laser on 1 m diameter Fresnel lens is numerically analyzed. Using of the Monte Carlo photon-tracing numerical method, three different pumping schemes were studied. The results showed that a large efficiency improvement in a multi-pass side-pumping scheme compared to the double-pass side-pumping scheme. The study demonstrated that the multi-pass side-pumping scheme can double the overall efficiency of solar double-pass side-pumped Nd:YAG laser.

太阳能泵浦激光器：带菲涅耳透镜的高效多通侧泵浦方案

摘要

对直径为1 m的菲涅耳透镜上的太阳能泵浦Nd：YAG激光器的多通侧泵浦方案进行了数值分析。使用蒙特卡洛光子跟踪数值方法，研究了三种不同的泵浦方案。结果表明，与双通旁抽方案相比，多通旁抽方案的效率大大提高。研究表明，多通侧泵浦方案可以使太阳能双通侧泵浦Nd：YAG激光器的整体效率提高一倍。
