摘　　要：根据激光二极管纵向抽运Tm ,Ho:YLF激光器的能级跃迁和能量传递过程 ,在考虑能量传递上转换的情况下 ,建立了准三能级阈值速率方程 ,得出了激光器阈值的解析解 .给出了阈值与激光器设计参数的关系 ,并分析了能量传递上转换对激光器设计参数的依赖关系 .实验上得到了不同输出耦合透过率下的激光阈值 。Based on the energy transfer between ions and the transition between energy levels of diode-end-pumped Tm, Ho: YLF laser, under the consideration of energy transfer up-conversion, the threshold rate equations are given, and the analytical formulas of laser threshold are deduced from rate-equations. The relations between laser threshold and laser designing parameters are derived. The dependence of energy transfer up-conversion on the laser designing parameters is analyzed in detail. Experiments on Tm, Ho: YLF crystals are performed to validate the present model.
