摘要
推导了非稳态情况下固体激光器的输出光强表达式,在此基础上数值模拟了钕玻璃热容激光器的增益性能。分析表明,高抽运光强可使激光器工作在高提取效率范围;介质大的发射截面、高长径比则可以大大减小激光器的阈值能量;温度的影响在高抽运光强时不明显。另外,由于温度和热容激光器脉冲串输出方式的影响,总脉冲串输出能量在腔镜透射率上也将有一个优化值。
Abstract
The expression for output laser intensity of solid state laser under unstable state is deduced in theory. And the gain characteristics of Nd:glass heat capacity laser is stimulated on the basis of that expression. It is shown that high pumped intensity, large emission cross-section, high aspect ratio can increase the extraction efficiency. The influence of temperature on extraction efficiency can be ignored under high pumped intensity. In addition, the transmission ratio of cavity mirror has an optimum value because of the influence of temperature on the output of the pulse string.
