We demonstrate a dual-wavelength passively mode-locked soliton fiber laser based on the single-wall carbon nanotube saturable absorber. By using a simple scheme of adjusting the intracavity loss, the gain profile of the erbium-doped fiber laser is effectively controlled. Besides operating at a single wavelength, the laser is able to simultaneously generate sub-picosecond pulses at both ~1532 and 1557 nm wavelength. The mode-locking wavelength can also be quickly switched from one wavelength to the other by changing the intracavity loss with a tunable attenuator.
我们展示了一种基于单壁碳纳米管可饱和吸收体的双波长被动锁模孤子光纤激光器。通过采用一种简单的调整腔内损耗的方案，有效地控制了掺铒光纤激光器的增益分布。除了在单波长工作外，该激光器还能够在~1532纳米和1557纳米波长同时产生亚皮秒脉冲。通过使用可调衰减器改变腔内损耗，锁模波长也可以快速从一个波长切换到另一个波长。
