摘　　要：激光点火装置是低电压启动设备,为了保障激光意外输出时的安全性,需要光开关作为激光点火系统的保险与解除保险装置。为此介绍一种适用于较高功率激光点火装置中的光开关。该光开关采用了移动光纤式结构,适用于较大芯径光纤,具有较低的插入损耗。Laser ignition system is a low voltage starting device, in order to ensure the safety when the laser occurs unexpected output, optical switch is required for used as the safety and arming device for the laser ignition system. Consequently, an optical switch suitable for being used in high power laser ignition system is introduced. The switch has a unique structure with shifting large core fiber, and low insertion loss.
