摘　　要：提出了一种波长可开关掺铒光纤激光器,将相移光纤光栅(PSG)用作窄带滤波器,布拉格光纤光栅(FBG)用作反射镜,通过调谐FBG中心波长实现波长的可开关特性,采用反馈光纤环结构来增大激光器的自由光谱范围(FSR),室温下,得到了稳定的单波长和双波长激光输出,并且在一定范围内可调谐.A switchable wavelength erbium-doped fiber laser was proposed, in which PSG was used as a narrow band filter and FBG was uesd as a mirror. The switchable characteristic of the wavelength could be got by tuning the center wavelength of the FBG. FSR of the laser was broadened through utilizing a feedback fiber ring. Stable single - wavelength and double - wavelengh output was got at room temperature and it can be tuned in a certain range.
