主動鎖模光纖雷射之研製

Abstract

本論文中我們探討主動鎖模光纖雷射的理論與架設.在實驗上我們成功 地製作出利用電光相位調變器來產生鎖模作用的環狀主動鎖模摻鉺光纖雷 射,當調變頻率為417.6MHz時,可以產生重複率為835.2MHz,寬53.8ps,峰值 功率237mW的光脈衝.我們以變分法解主動鎖模光纖雷射的主方程式,並將 實驗和計算上的結果作一比較,發現結果相當符合. In the thesis we study the theory and construction of actively mode-locked fiber lasers. We have successfully constructed an actively mode-locked Er-dopedfiber ring laser using an E-O phase modulator as the mode-locker. When the modulator is driven by a 417.6 MHz RF signal, pulses with a duration of 53.8 psand peak power of 237 mW are generated at a repitition rate of 835.2 MHz. We have also solved the master equation of the actively mode- locked fiber laserby means of a variational method and compared the calculated results with theexperimental results. Good agreement is found.
