摘　　要：在自制掺铒光纤飞秒锁模激光器的基础上,通过将自由光谱宽度为4.77 GHz的法布里-珀罗腔(F-P腔)模式滤波器的谐振频率点锁定到飞秒激光的一组模式上,实验实现了4.77 GHz高重频飞秒脉冲激光的产生。该实验采用Tilt-Lock方法实现了F-P腔锁定,并获得0.246 mW的模式滤波输出,重复频率与原有飞秒脉冲激光相比提升23倍。A high repetition-rate femtosecond pulse laser source, based on a Fabry-Perot（F-P） modefiltered cavity with a free spectral range（FSR） of 4.77 GHz and a home-made femtosecond erbium-doped fiber mode-locked laser, is designed by applying the Tilt-Lock technique. The F-P cavity is locked so that only the laser modes with a frequency being multiples of the cavity FSR can be transmitted. Through such implementation, a 4.77 GHz repetition-rate femtosecond laser pulses is realized with a transmission power of 0.246 m W. Compared with the input pulse source, the repetition rate is 23 times higher than that of the original femtosecond laser.
