带有保护功能的半导体激光器稳流源

The Power of Semiconductor Laser with Stabilization Current and Protective Function

介绍一种半导体激光器专用电源的设计 ,此电源电路可有效防止电源开关过程中电流的瞬时冲击对激光器的损坏 ,并能在供电过程中使电流达到相当稳定的幅值 。

In this paper, a kind of the special power design of semiconductor laser is discussed. This circuit can effectively protect the laser from the bad current instantaneous impact in the course of power's opening or closing, and at the same time provide the stable current. So this circuit not only can provide power for semiconductor laser, but also can effectively protect the laser.
