本論文中我們在10 GHz非同步諧波鎖模摻鉺光纖雷射下透過改變調變頻率大小成功演示非同步諧波鎖模與頻率調變震盪態之過渡,同時也利用數值模型模擬在不同調變頻率下雷射的狀態,此外也針對在頻率調變震盪狀態下進行腔外脈衝壓縮的實驗與模擬,結果有很好的吻合性。
In this thesis, we successfully demonstrate the asynchronous harmonic mode-locking and frequency modulation (FM) oscillation transition with increasing detuning frequencies in a 10 GHz hybrid mode-locked Er-doped fiber laser. We also simulate the states of lasing under different detuning frequencies as well as the external pulse compression results under the FM oscillation state. The experimental and simulation results are in good agreement.
