| 摘 要： | 光纤M-Z干涉仪是由两个3dB耦合器构成,将此干涉仪放到激光腔中通过调节其干涉状态就可以相应地调制激光腔的损耗,发挥Q开关的作用。从理论上模拟了M-Z干涉仪输出光强随相位差的改变而发生平移,并在实验中验证了这一特性,证明理论模拟的特性与实验基本符合。

| Abstract: | A Mach-Zehnder interferometer is formed with two 3-dB couplers. The laser cavity loss being modulated and bringing Q-switch into play can be carried out through locating the interferometer into the laser cavity and adjusting its interference state. The translation occurred in output light intensity of Mach-Zehnder interferometer during phase difference variation is simulated in theory and this property is demonstrated by experiments. This proves that the theoretical simulation property is basically consistent with the experiments. |
