We demonstrate an enhanced multiwavelength L-band Brillouin-erbium fiber laser (BEFL), in which the Brillouin pump is pre-amplified before entering the single-mode fiber. The Brillouin pump pre-amplification provided by the Erbium-doped fiber has created higher intensity of Brillouin Stokes line generated in the single-mode fiber that leads to the homogenous gain saturation. Thus the built-up of self-lasing cavity modes is suppressed in a wider wavelength range. In contrary to the conventional linear-cavity BEFL, the number of output channels is enhanced within the same tuning range.
我们展示了一种增强型多波长L波段布里渊-铒光纤激光器（BEFL），其中布里渊泵浦在进入单模光纤之前进行了预放大。掺铒光纤提供的布里渊泵浦预放大在单模光纤中产生了更高强度的布里渊斯托克斯线，从而导致均匀的增益饱和。因此，在更宽的波长范围内抑制了自激腔模的形成。与传统的线性腔BEFL相反，在相同的调谐范围内输出通道的数量增加了。
