论文摘要
在本文中，从每个能级的活动粒子的周期（泵浦时间，放松时间和刺激的排放时间）的新角度来看，引入了激光介质的迭代泵送数量的概念，以及当它在稳态下发出光线时，激光模型的等效模型。通过得出发光时在光出口区域反复泵送激光介质的次数，推导激光输出功率的分析表达，并获得激光输出功率的定律随激光参数而变化。通过拟合并与实验结果进行比较，新模型和实验结果良好，获得的相关参数也与文献非常一致，并且获得了多个参数和温度的变化。这些结果，特别是用于分析激光输出功率的表达式，一种用于研究和设计光泵激光器的新方法。
In this paper, from a new perspective of the time (pump time, relaxation time, and stimulated emission time) of the cycle for the active particles at each energy level, the concept of the number of iterative pumping of the laser medium is introduced, and the equivalent model of the laser when it emits light in a steady state is established. By deriving the number of times that the laser medium is repeatedly pumped in the light exit area when the light is emitted, the analytical expression of the laser output power is deduced, and the law of the laser output power changing with the laser parameters is obtained. By fitting and comparing with the experimental results, the new model and the experimental results are in good agreement, the related parameters obtained are also very consistent with the literature, and the changes of multiple parameters and temperature are obtained. These results, especially the expression for the analysis of the laser output power pave a new way for the research and design of optical pumped lasers.
