We report the generation of tunable single- and dual-wavelength dissipative solitons in an all-normal-dispersion mode-locked Yb-doped fiber laser, to the best of our knowledge, for the first time. Besides single-wavelength mode-locking, dual-wavelength mode-locking was achieved using an in-line birefringence fiber filter with periodic multiple passbands, which not only allows multiple wavelengths to oscillate simultaneously but also performs spectrum modulation on highly chirped dissipative pulse. Furthermore, taking advantage of the tunability of the birefringence fiber filter, wavelength tuning for both single- and dual-wavelength dissipative soliton mode-locking was realized. The dual-wavelength operation is also switchable. The all-fiber dissipative laser with flexible outputs can meet diverse application needs.
据我们所知，我们首次报道了在全正色散锁模掺镱光纤激光器中产生可调谐单波长和双波长耗散孤子。除了单波长锁模外，还利用具有周期性多通带的在线双折射光纤滤波器实现了双波长锁模，该滤波器不仅允许多个波长同时振荡，还对高啁啾耗散脉冲进行光谱调制。此外，利用双折射光纤滤波器的可调谐性，实现了单波长和双波长耗散孤子锁模的波长调谐。双波长操作也是可切换的。这种具有灵活输出的全光纤耗散激光器可以满足各种应用需求。
