摘　　要：双包层光纤激光器不再要求抽运光是单模激光 ,而且基本上在沿光纤整个长度上抽运 ,从而大幅度地提高了激光转换效率。给出了一种由半导体激光器 (LD)抽运的掺Yb3 +双包层光纤激光器 ,利用 976nm的抽运光 ,对双包层光纤进行端抽运 ,光纤后端与双色镜构成Fabry Perot干涉仪兼作反馈腔镜 ,得到波长为 10 85nm ,10 90nm ,10 95nm和 110 0nm的激光输出 ,每个波长激光的线宽为 0 33nm ,输出总激光功率为 1 2W ,信噪比超过 2 0dB ,斜率效率为 5 2 %。For the double clad fiber laser, differ from ordinary fiber laser, the requirement of a single mode for pumping the fiber laser is needless, furthermore, the pump beam coupling into fiber along nearly whole fiber, consequently, the laser conversion efficiency is improved. In this paper, a novel Yb 3+ doped multi wavelength double clad laser pumped by 976 nm laser diode is presented. The output wavelength are 1085, 1090, 1095 and 1100 nm. The laser exhibits 0.33 nm line width, 1.2 W laser out power, 20 dB signal to noise (SNR) and 52% slope efficiency.
