摘要
自主研制了基于掺铒光纤飞秒激光技术的光纤飞秒光学频率梳。详细介绍了此光纤光梳的系统结构、工作过程与各项性能参数。经过功率放大、色散优化与高非线性光纤扩谱等过程,得到了超过一个倍频程的光梳超连续光谱。光梳的载波包络偏移频率(简称偏频,f_o)从f-2f共线式干涉系统中提取,并锁定至铷原子钟上。实验获得了35dB信噪比的偏频信号,实现了锁定时间超过12h的稳定运转。
A home-made fiber comb is developed based on the technology of Erbium-doped fiber femtosecond laser. The system configuration, working process and performance parameters of this comb are described in detail. A supercontinuum more than one octave is obtained after power amplification, dispersion optimization and spectrum spreading in highly nonlinear fibers. The carrier-envelope offset frequency （fo） is extracted by means of a linear f-2f interferometer and locked to a Rubidium atomic clock. The observed signal-to-noise ratio of fo is 35 dB and steady operation with locking time more than 12 h is demonstrated.
