摘要
本文首次对高功率GaAs/GaAlAs量子阱激光器 ( 80 8nm)的低频 ( 10 0Hz～ 2 0KHz)电流调制特性进行了实验研究。结果表明 :激光发射的接通延迟时间、阈值电流、正脉冲的占空比、平均功率。
In this paper,the current modulation characteristics of a high power GaAs/GaAlAs quantum well laser in low frequencies(100Hz～20KHz)were experimentally investigaed in the first time.The result showed that the laser characteristics,such as the open delay time,the threshold current,the positive duty cycle,the average power and the peak power changed with the modulation frequency and the modulation current.
