Abstract

It is shown that direct measurements of the gain of weak signals of an active element irradiated by a probe laser can give a result much lower than that measured by the lasing threshold. A possible cause of such disagreement is discussed.

在Nd：YAG有源介质中测量固态二极管泵浦激光增益模块的微弱信号增益的技术比较

摘要

结果表明，直接测量由探测激光器照射的有源元件的微弱信号的增益所得到的结果要比通过激光阈值所测量的结果低得多。讨论了这种分歧的可能原因。
