Examination of various issues related to the generation and application of optical frequency combs (OFCs) is an important branch of modern optoelectronics. Some of the proposed OFC generation methods apply acousto-optic (AO) devices. The AO devices are used either as the element devoted to the OFC phase stabilization or they play the role of an optical radiation frequency shifting element in the frequency-shifting loop (FSL) scheme. The results of two experiments related to the application of AO cells in the FSL scheme are represented in this paper. The first experiment confirms the previously proposed effect of AO mismatch influence on all the OFC characteristics. The second experiment shows the possibility of tunable AO dual-comb downconversion with a single AO device.
对与光频梳（OFC）的产生和应用相关的各种问题进行研究是现代光电子学的一个重要分支。一些提出的光频梳产生方法应用了声光（AO）器件。这些声光器件要么用作专门用于光频梳相位稳定的元件，要么在移频环（FSL）方案中充当光辐射频移元件。本文展示了与声光单元在移频环方案中的应用相关的两个实验结果。第一个实验证实了先前提出的声光失配对所有光频梳特性的影响。第二个实验展示了使用单个声光器件实现可调谐声光双梳下变频的可能性。
