我们报告了一种基于全光纤线性腔中多模干涉滤波效应的可切换和间距可调的双波长时空锁模（STML）激光器。实现了与不同脉冲模式相结合的双波长STML操作。通过调节偏振控制器，双波长 STML 脉冲可以切换为单波长操作，在一定泵浦功率下可调谐至 35 nm。此外，双波长间距还可在8 nm至22 nm之间调节。获得的结果有助于理解和探索 STML 光纤激光器在多波长范围内工作的时空特性。具有激光波长可调性和灵活性的全光纤STML激光器可能在光通信和光学测量领域有应用。
We report a switchable and spacing tunable dual-wavelength spatiotemporal mode-locked (STML) laser based on the multimode interference filtering effect in an all-fiber linear cavity. The dual-wavelength STML operations combined with different pulse patterns are achieved. By adjusting the polarization controllers, the dual-wavelength STML pulses can be switched to single wavelength operation, which is tunable up to 35 nm under certain pump powers. Moreover, the dual-wavelength spacing can also be tuned from 8 nm to 22 nm. The obtained results contribute to understanding and exploring the spatiotemporal characteristics operating in the multi-wavelength regime of STML fiber lasers. All-fiber STML lasers with lasing wavelength tunability and flexibility may have applications in the fields of optical communications and optical measurements.
