Abstract

A way is proposed for measuring the rate of degradation of a high-power continuous-wave laser diode with a wide contact by monitoring the state of its heterostructure every 50 h of operation. The number and structure of the channels of laser generation is used as a controlled parameter. The mechanism of the laser diode structure’s degradation is considered in the time dependence of the number of lasing channels.

根据辐射光谱对泵浦电流变化的依赖性确定高功率激光二极管的降解速率

摘要

提出了一种通过每工作50小时监测其异质结构状态来测量具有大接触量的大功率连续波激光二极管的退化速率的方法。激光产生通道的数量和结构被用作受控参数。激光二极管结构退化的机理是根据激光通道数量的时间依赖性来考虑的。
