| 本研究成功搭建了一种基于半导体可饱和吸收体的可调谐双波长锁模光纤激光器。通过波分复用器和保偏光纤之间的角度拼接，在腔体内产生了临界周期性Lyot滤波效应。实验表明，通过调节泵浦功率及偏振控制器，该激光器实现了连续可调谐单波长和异步双波长两种模式的切换输出。在单波长工作模式下，输出波长可在 1556~1570 nm 范围内连续调谐；在异步双波长工作模式下，受到腔体色散的影响，腔体内异步脉冲序列之间的重复频率差可在 152~425 Hz 范围内进行调节。该系统具有较好的稳定性，结构紧凑且配置操作简单、稳固，为双光梳光谱学提供了更多的实际应用。 |

| This study demonstrates a tunable dual-wavelength mode-locked fiber laser based on a semiconductor saturable absorber. By employing angular splicing between a wavelength division multiplexer and polarization-maintaining fiber, a critical periodic Lyot filtering effect is generated within the cavity. Experimental results indicate that by adjusting the pump power and polarization controllers, the laser achieves switchable output between continuously tunable single-wavelength and asynchronous dual-wavelength operation modes. In the single-wavelength mode, the output wavelength can be continuously tuned from 1556 nm to 1570 nm. In the asynchronous dual-wavelength mode, influenced by the cavity dispersion, the repetition frequency difference between the asynchronous pulse trains can be adjusted within the range of 152 Hz to 425 Hz. The system exhibits good stability, compact structure, and simple, robust configuration, offering enhanced practical applicability for dual-comb spectroscopy. |
