摘　　要：研究了一种基于光纤Sagnac环镜的多波长线性腔掺铥光纤激光器。该激光器采用1.5 m长的双包层掺铥光纤为增益介质,793 nm激光二极管为泵浦源,光纤Sagnac环镜和光纤环形镜构成激光器谐振腔。通过增加泵浦功率和调节偏振控制器,在1 949~1 976 nm的光谱范围内实现了1~7个波长的激光输出,输出功率达毫瓦量级,光信噪比达到40~50 dB。A multi-wavelength linear cavity thulium-doped fiber laser based on fiber Sagnac loop mirror is studied. A 1.5 m long double-clad thulium-doped fiber is used as the gain medium, and a 793 nm laser diode is used as the pump source. The fiber Sagnac loop mirror and the fiber ring mirror constitute the laser resonant cavity.By increasing the pump power and adjusting the polarization controller, laser outputs with 1~7 wavelengths are realized within the spectral range between 1 949 and 1 976 nm. The output power is on the order of milliwatts, and the optical signal-to-noise ratio reaches 40~50 dB.
