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。
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.
