摘要

在這篇論文中我們使用一般線型光纖雷射共振腔為主軸，將其共振腔加入薩格納克(Sagnac)干涉儀與壓電陶瓷(PZT)，利用兩者特性產生週期性損耗來達到主動鎖模進而產生脈衝，並藉由改變整個共振腔長度來達到調整光脈衝週期的效果。在本研究中，我們產生22μs、44μs、88μs週期的光脈衝，也比較了訊號產生器給的方波訊號與正弦波訊號對於光脈衝的影響，最後探討環境對於此架構的影響，分別做了光纖脈衝對聲音、溫度、拍擊干擾時的表現。

In this paper, we incorporate a Sagnac interferometer and a PZT in a fiber-optic linear-type laser cavity. We use the Sagnac interferometer and the PZT to generate periodic cavity loss and active mode-locking, and then generate pulses. We modify the length of the Sagnac interferometer to adjust the period of the optical pulse train, in generating optical pulses of several hundred nanoseconds in width. We then compare the influence of the square wave signal and the sine wave signal given by the signal generator on the light pulse. Finally, a discussion on the influence of the environment, which includes the sound, temperature and vibration, on pulse generation is given.
