摘要
由跃迁速率方程推出了三能级系统的激光阈值和斜率效率解析式.根据测试的吸收谱,计算了YAG晶体中Er3+离子的吸收截面.分析了16μm波长的激光特征.
AbstractThe analytical formulas of laser threshold,slope efficiency of a three energy level system are deduced from rate equations of transitions.The absorption cross section of Er^3+ ions in YAG crystal is calculated according to measured absorption spectrum.The characteristics of laser at 16μm wavelength are analysed.
