提出了一种利用高双折射光纤中写入的级联光纤布拉格光栅(FBG)实现多波长可切换运转的新型、简单的掺铒光纤激光器。由于FBG的双峰反射与偏振正交，极大地增强了腔内的偏振烧孔效应。实验结果表明，在室温下可以获得稳定的双波长和三波长激光运转，波长间隔非常窄(∼为0.39 nm)。配置简单灵活。只有通过调节偏振控制器(PC)，激光器才能在稳定的单波长、双波长和三波长激光操作之间切换。
A novel and simple Erbium-doped fiber laser by using cascaded fiber Bragg gratings (FBGs) written in high-birefringence fibers for switchable multi-wavelength operation is proposed. Due to two-peak reflection with orthogonal polarizations of the FBG, the polarization hole-burning effect in the cavity is greatly enhanced. Experimental results show that the stable dual- and three-wavelength lasing operation with very narrow wavelength separation (∼0.39 nm) can be generated at room temperature. The configuration is simple and flexible. Only by adjusting polarization controllers (PCs), the laser can be switched among the stable single-, dual- and three-wavelength lasing operations.
