摘要
由激光晶体的准三能级速率方程出发，在不同条件下对激光二极管抽运的Yb：YAG激光器的输出功率和阈值功率随着空间变量、晶体长度、透过率、往返损耗等影响下的输出特性进行了理论分析和数值模拟计算，在不同输入功率与阈值功率比值条件下，得到了振荡光斑与泵浦光斑比值为1．5、晶体长度为0．2～0．4cm、相对透过率为1．5时均有最大输出功率和最小的阈值功率。
Based on the theory of quasi-three-level rate equation, the theoretical analysis and simulation of output power and threshold power of Yb： YAG laser have been obtained. The results of the relative curves on the output power and threshold power with the spatial characteristic parameters, crystal lengths, transparency rate, and loss of round-trip of laser-diode-pumped all-solid-state Yb：YAG laser were presented. The high power output and low threshold power were calculated when a 1.5 rate of resonant beam to pump beam facula, 0.2 - 0.4cm of crystal lengths, and 1.5 rate of transparency in the paper.
