摘　　要：针对现有光纤激光器调谐方法通常不能兼顾调谐幅度和调谐速率的问题,提出了一种基于光热效应的调谐方法,有效兼顾了调谐幅度和调谐速率的要求。分析了光纤激光器的输出波长随泵浦功率变化而改变的实验现象,并以980nm泵浦源自身调谐为例,进行了静态和动态实验,结果表明:基于光热效应的分布反馈式光纤激光器静态调谐幅度达392MHz/100mA,动态调谐速率超过2kHz,验证了光纤激光器光热调谐方案的可行性。The existing tuning methods of fiber lasers are researched, and they usually cannot take into account the require- ments of the tuning range and tuning rate. To solve this problem, a new tuning method based on the photo-thermal effect is pro- posed, the experimental phenomenon shows that the output wavelength of fiber lasers varies with the pump＇s power. The static and dynamic tuning characteristics of fiber lasers reveal that the tuning range is about 392 MHz/100 mA and the tuning rate is more than 2 kHz in 980 nm pump source self-tuning. The feasibility of this tuning method has been verified.
