摘要：

A design and development technique for optical frequency comb based on femtosecond fiber laser is proposed. A dispersion-managed solution mode-locked erbium-doped fiber laser with pulse width of 55 fs and frequency of 210 MHz is designed, and the chirped pulse fiber amplification link is optimized. An octave supercontinuum from 1080 nm to 2320 nm is generated by a fiber with high nonlinear, which makes the signal-to-noise ratio of the detected carrier-envelope offset frequency reach 32 dB by the f-2f (f represents frequency) autodyne method. When the 4th harmonic wave of repetition rate and the carrier envelope offset frequency are locked to a commercial rubidium atomic clock, an optical frequency comb is locked with high precision. Measurement results show that the standard deviations of repetition rate and carrier envelope offset frequency are 0.65 mHz and 1.76 mHz at 1 s counter gate time, corresponding to the Allan deviations of 1.74×10-13 and 1.80×10-11 for 100 s sampling time, respectively. Such a fiber optical comb may meet applications in fields of optical frequency metrology, optical comb spectroscopy, timing and frequency transfer, microwave generation and so on. © 2017, Chinese Lasers Press.
