1. Inversion without lasing can also occur when the conditions are changed.
   在另一条件下，系统则能够呈现无激光反转。
2. The hybrid gain medium can also increase the lasing bandwidth compared with a pure EDF laser, and improve the power conversion efficiency compared with a pure fiber Raman laser.
   与纯掺铒光纤激光器相比，该混合增益介质同样能够增加激光带宽，而与纯光纤拉曼激光器相比，该混合增益介质也能够改善激光器的功率转化效率。
