半导体激光纵向泵浦的光学耦合系统设计
Design for Optical Coupler in Diode Laser Longitudinal Pumped Solid-State Lasers
摘要
提出了半导体激光泵浦光束在固体增益介质内的加权平均半径是影响泵浦效率的主要参数；分析了泵浦光束尺寸、椭圆率与斜率效率和阈值的关系。从分析模式匹配理论出发,提出了光学耦合系统的设计和调整应满足的条件,最后对棱镜扩束耦合系统进行了详细计算和简单的实验研究。
Abstract
In the P8per the concept of average radii of pumped beam in a solid medium being a criteria of efficiency is presented. Dependences of slope and threshold on volume and ellipticity of pumped light are analysed. Based on the theory of mode-coupling,requirements of a coupling system for design and adjustment are deduced, Finally a coupling system consiting of a couple of expanding prisms is investigated in detail.
