中文摘要：

一面非线性的光环镜子(NOLM ) 基于线性洞可切换的多波长做耳的纤维(EDF ) 激光被建议并且试验性地示威了。由于紧张依赖者 transmissivity 的特征， NOLM 能有效地减轻同质的拓宽获得媒介的模式比赛，以便放射激光的多波长能在房间温度被完成。由调整极化控制器(PC ) 的状态，在建议激光罐头的放射激光的波长的数字在 1 530 nm 的波长附近与 0.4 nm 的波长间距从 11 ～ 13 灵活地被调整。

英文摘要：

A nonlinear optical loop mirror（NOLM）-based linear cavity switchable multi-wavelength erbium-doped fiber（EDF） laser is proposed and experimentally demonstrated.Due to the characteristics of the intensity-dependent transmissivity,the NOLM can effectively mitigate the mode competition of the homogenous broadening gain medium,so that the multi-wavelength lasing can be achieved at room temperature.By adjusting the states of the polarization controllers（PCs）,the number of the lasing wavelengths in the proposed laser can be adjusted flexibly from 11 to 13 with a wavelength spacing of 0.4 nm around the wavelength of 1 530 nm.
