本論文建立了載波包絡相位穩定的飛秒光纖雷射，使用極化保持光纖的架構得到脈衝寬度110 fs，脈衝重複率47 MHz與脈衝能量為13.4 nJ的自啟動雷射後，利用光子晶體光纖產生超連續光譜，並以f-to-2f干涉儀量測載波包絡偏移頻率，再藉由比例積分微分控制(PID control)回授雷射泵浦電流以穩定載波包絡相位。穩定時所測得之相位噪音為2.3 rad[由3.3 kHz積分至1 MHz]。

We constructed a carrier-envelope-phase-stabilized fiber laser, with a repetition rate of 47 MHz, pulse duration of 110 fs and pulse energy of 13.4 nJ in an all polarization maintaining architecture. A photonic crystal fiber was used for supercontinuum generation, and a f-to-2f heterodyne setup was used for carrier-envelope-offset frequency detection. Then a feedback system based on proportional-integral-derivative control was used to stabilize the offset frequency through tuning the pump current of the oscillator. The phase noise of the stabilized f_CEO beat was reduced to below 2.3 rad [integrating from 3.3 kHz to 1 MHz].
