摘　　要：介绍了一种基于电光晶体马赫-曾德尔干涉仪的载波包络相移快速调节方法,对此方法进行了理论分析和仿真计算,并搭建了一套基于电光晶体马赫-曾德尔干涉仪的载波包络相移调节的光梳实验系统。与超稳激光进行拍频以验证其调节效果,证明可实现8 MHz的载波包络相移调节范围,为窄光梳的实现提供了一种技术手段。We introduce the technique of narrow-linewidth optical frequency combs.A method based on the MachZehnder Interferometer with electro-optic modulators was demonstrated to be able to fast control the carrier-envelope offset frequency.A relevant theoretical analysis and simulation were carried out.An experimental frequency comb based on the Mach-Zehnder Interferometer with electro-optic modulators was built in our lab.An ultra-stable laser with the linewidth of about 1 Hz was employed to beat with the comb to verify the capability of the Mach-Zehnder Interferometer.A carrierenvelope offset frequency shift of about 8.2 MHz was achieved.This method provides a technical solution for narrowlinewidth optical frequency combs.
