voltage surge

Briefly describe the necessity of developing voltage surge protection device.

概述了开发低压避雷电器(过压保护器)的必要性.

The power magnitude and stability of LD output is related to the drive current, LD can be damaged due to voltage surge. So besides making the current value of LD constant, we also must take appropriate means to protect it.

LD的输出光功率大小及稳定性与驱动电流有关，同时，LD还易受浪涌电压而损坏，因此除使注入LD的电流保持恒定外，还应采取相应的保护措施。
