We report on the wavelength-switchable operation of multiple solitons and dissipative soliton resonance (DSR) in C- and L-band fiber lasers. Mode-locking operations can be alternatively switched between 1565 nm and 1604 nm with adjustments to the polarization controller. Through controlling the intracavity filtering effect, tunable operations have been observed from 1563.7 nm to 1574.6 nm and from 1600.3 nm to 1605.7 nm. More importantly, the fiber laser operated at the 1565 nm waveband tended to generate multiple solitons, whereas one operated at the 1604 nm waveband tended to generate a rectangular DSR. Our investigations may contribute to understanding complex soliton dynamics in fiber lasers.

C波段和L波段锁模光纤激光器中的多个孤子的可切换操作和耗散孤子共振

我们报告了在C波段和L波段光纤激光器中，多个孤子的波长可切换操作和耗散孤子共振（DSR）。可以通过调整偏振控制器在1565 nm和1604 nm之间切换模式锁定操作。通过控制腔内滤波效果，可以观察到从1563.7 nm到1574.6 nm和从1600.3 nm到1605.7 nm的可调操作。更重要的是，在1565 nm波段工作的光纤激光器倾向于产生多个孤子，而在1604 nm波段工作的光纤激光器则倾向于产生矩形DSR。我们的研究可能有助于理解光纤激光器中的复杂孤子动力学。
