| 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(ETU)的情况下，建立了Tm,Ho：YLF主动调Q激光器的准三能级速率方程，得出了激光单脉冲能量的解析表达式.在理论上指出，能量传递上转换不但减小了输出单脉冲能量，而且严重减小了激光上能级寿命.实验上给出了在固定抽运功率下，单脉冲能量随重复频率的变化关系，验证了理论所指出的能量传递上转换减小了激光上能级寿命.关键词：二极管抽运TmHo：YLF晶体能量传递上转换速率方程

| Abstract: | Based the energy transfer between energy levels and the transition between ions of diode-end-pumped Tm,Ho:YLF laser, with consideration of energy transfer up-conversion, the rate equations of Tm,Ho:YLF Q-switched laser are given, and the analytical formulas of single pulse energy is deduced from the rate-equations. It is shown theoretically that the energy transfer up-conversion reduces not only the single pulse energy but also the upper level lifetime of Tm,Ho:YLF Q-switched laser. An experiment is carefully designed to verify these conclusions. |
