摘　　要：基于差频技术的单块飞秒光学频率梳被广泛应用于光频的精密测量领域。通过将飞秒激光的重复频率和载波包络相移同时锁定至原子钟上,可以将飞秒光学频率梳的稳定状态延长至9 h。文中提出了一种基于飞秒光学频率梳的双通道光频测量设计,并且针对两种待测光频的不同情况,给出了不同的测量方法。这种设计对将来实现高效率的光频测量具有重要意义。A monolithic femtosecond optical frequency comb（FOFC） based on the difference frequency technique was introduced in the optical frequency measurement.Long-term stabilization of more than 9 hours was demonstrated by simultaneously locking repetition rate and carrier envelope offset to an atomic clock.Furthermore,a multichannel optical frequency measurement scheme with a monolithic FOFC was proposed.For measuring two different optical frequencies,the multichannel measurement apparatus is composed of FOFC and transmissive grating（or narrow band high reflectivity mirror） in the experimental apparatus.The scheme would be helpful for the realization of high efficiency optical frequency measurement.
