摘　　要：为了研究温度对光纤激光器输出性能的影响,构建了一种自种子直线腔光纤激光器。该激光器采用掺铒光纤作为腔内放大增益介质,并利用光纤布喇格光栅(FBG)和光纤环镜组成线形激光腔。通过改变腔中核心器件的温度对激光器进行了实验研究。实验结果表明:随着温度的升高,激光器波长线性增加;与FBG自身加热时激光器的输出波长变化相比,激光器波长额外红移0.05243 nm。当温度从25℃升高至55℃时,激光器输出转换效率降低了4.878%,输出功率降低了33%。In order to study the effect of temperature on the output performance of fiber lasers,a self-seeded linear cavity fiber laser is constructed.The laser uses erbium-doped fiber as the gain medium,and uses fiber Bragg grating(FBG)and fiber ring mirror to form a linear laser cavity.The laser is experimentally studied by changing the temperature of the core device in the cavity.The experimental results show that the laser wavelength increases linearly with the increase of temperature.Compared with the change of the output wavelength of the laser when the FBG itself is heated,the laser wavelength is redshifted by 0.05243 nm.When the temperature is increased from 25℃ to 55℃,the output conversion efficiency of the laser is reduced by 4.878%,and the output power is reduced by 33%.
