Abstract :
Perfect linkage of dual frequency combs based on all polarization-maintaining femtosecond fiber lasers is demonstrated. By employing two independent tracking feedback controlling circuits, the repetition frequency (fr) and the carrier-envelope offset frequency ( fceo) of the slave frequency comb track the master´s fr and fceo, respectively. The correlation coefficients of the dual fr´s and the dual fceo´s are up to 0.99 and 0.98, which indicate an ideal linkage between the dual frequency combs. To the best of our knowledge, this is the first report about linkage of dual frequency combs.
