摘　　要：针对高分辨双光梳光谱技术对光梳相干性的严苛要求,提出了一种双光梳同源锁频的方法。该方法将两台光纤光梳锁定在一台相位调制连续激光器的两个频率边带上,使双光梳具有相同的光学参考标准,因此无需复杂的相位修正电路和超稳光学腔,可获得高时频相干性,相干时间长达1 s。经过实验验证,该方法获得了梳齿可分辨的双光梳频谱信号。In order to meet the requirement of high-resolution dual-comb spectroscopy for the mutual coherence of optical combs,a method of dual-comb homologous frequency stabilization is proposed,that is,two optical fiber combs are locked on two frequency sidebands of the same phase modulated continuous wave laser.This method makes the two combs have the same optical reference,so there is no need for complex phase correction circuit and ultra-stable optical cavities.The coherence time is greater than 1 s.After experimental verification,this method obtains the comb-line-resolved dual-comb spectrum signal.
