The Numerical Analysis of Tm:YAP Slab Laser
摘要
建立了在双端泵浦Tm:YAP板条晶体条件下激光能级跃迁的准三能级速率方程模型。通过对准三能级速率方程进行求解, 数值仿真了晶体温度分布、上转换效应、泵浦光斑尺寸以及输出镜透过率等参数对Tm:YAP板条激光器输出功率的影响, 为高功率Tm:YAP板条激光器的设计提供必要的数值分析基础。
Abstract
The quasi-three energy levels laser rate equation model of Tm:YAP slab pumped by two fiber coupled diode lasers is developed. Based on the solution of the equation, the influence on Tm:YAP laser output power is simulated, including the working temperature distribution of the crystal, up-conversion effect, the appropriate range of the spot radius and the transmission efficiency of output lens. It provides the necessary numerical analysis basis of designing the high power Tm:YAP slab laser.
