摘要
窄脉冲光功率恒定控制器采用光纤、分束器、光电转换器等常用的器件,对高功率纳秒级脉宽的光脉冲信号进行脉宽展宽,在总能量基本保持不变的情况下将光脉冲信号转变成一个低功率、微秒级脉宽的光脉冲信号,便于测量、跟踪,实现纳秒级脉宽光脉冲信号的自动恒功率控制,极大地提高了窄脉冲光功率的稳定性。
Constant-power controller for narrow pulse adopts common components including fiber,splitters and E/O converters.It is used to broaden the optical pulse signal with high power and ns duration,and convert the optical pulse signal into a low power pulse withμs duration in the case of basically equal total energy,so that it can measure, track and implement automatic constant-power control of huge power and ns pulse,thereby significantly improving the stability of the output.
