全光纤色散腔掺铒光纤激光器

Er 3+ Doped Fiber Laser with All Fiber Dispersive Cavity

报道用９７１ｎｍ半导体激光器泵浦的掺铒光纤激光器的一些实验研究结果。演示了由光纤环反射器和光纤光栅构成的全光纤色散腔掺铒光纤激光器，在１．５５μｍ波段获得了线宽小于０．０５ｎｍ的激光输出。

Some experimental results on Er 3+ doped fiber laser pumped by a 971 nm semiconductor laser are reported. A fiber laser with all fiber dispersive cavity formed by a fiber loop reflector and a fiber grating is proposed and successfully demonstrated. Laser output with linewidth narrower than 0.05 nm at 1.55 μm waveband is obtained.
