利用具有略微不同的重复率的两个脉冲序列的双光学频率梳最近在距离测距（LIDAR）、结构健康监测、气体传感、光学通信和天文学仪器校准中得到了应用[1]，[2]。目前，在光纤激光器和固体激光器中产生双光频梳的方法有很多种。尽管如此，基于两个同步超快激光器的传统实现方式需要解决几个技术挑战，例如两个激光器之间锁相的复杂性。因此，大多数研究工作最近已转向基于单个激光器的更简单的系统。单光源双梳（双梳激光器）在抑制共腔噪声和共腔中梳的相干性方面具有一定的优势[3]，[4]。
Dual optical frequency combs exploiting two pulse trains with slightly different repetition rates have recently found applications in the distance ranging (LIDARs), structural health monitoring, gas sensing, optical communications, and instrumentation calibration for astronomy [1], [2]. To the date, there are various ways to generate dual optical frequency combs both in fiber lasers and solid-state lasers. Nonetheless, the traditional implementations based on two synchronized ultrafast lasers require addressing several technical challenges, such as the complexity of the phase-locking between both lasers. Therefore, most research efforts have been recently re-directed towards simpler systems based on a single laser. Single source dual-comb (dual-comb laser) has some advantages when it comes to common noise suppression and combs' coherence in a shared cavity [3], [4].
