摘要: 为了得到1080nm的小型化、高功率、连续型光纤激光器,以915nm的半导体激光二极管(LD)作为泵浦源,由2个光纤光栅构成谐振腔;以12m掺镱双包层光纤作为增益介质,结合合束器、剥模器、准直器等光纤器件,搭建了全光纤结构的激光器系统。当泵浦功率达到118W,实验得到了功率为80W、光光转换效率为68%的连续且稳定的激光输出。将激光器系统组装到自行设计的紧凑型长方体铝制外壳内,光纤激光器总重量小于1.8kg,体积为200mm×160mm×40mm,能够稳定工作在-40~50℃环境下。

Abstract: In order to obtain a 1080nm miniaturization, high power, continuous fiber laser, a 915nm semiconductor laser diode (LD)is used as the pump source, and the resonant cavity is composed of two fiber gratings.Combining with beam combiner, stripping mold, collimator and other optical devices, anall fiber laser system is constructed using 12m Yb-doped double cladding fiber as the gain medium. When the pump power is up to 118W, a continuous and stable laser output with a power of 80 Wand an optical conversion efficiency of 68% is obtained experimentally.The laser system is assembled into a self-designed compact cuboid aluminum housing.The total weight of fiber laser is less than 1.8 kg, and the volume is 200mm ×160mm×40mm. It can work stably in environment ranging from -40℃ to 50 ℃.
