110 W高功率高亮度915 nm半导体激光器光纤耦合模块研究(英文)

110 W High Power and High Brightness 915 nm Fiber Coupled Laser Diode Module

利用空间合束技术和光纤耦合技术将9只波长为915 nm单管芯半导体激光器高效率耦合进光纤中,制备出具有高功率、高亮度输出光纤耦合模块。应用ZEMAX光学软件进行模拟仿真后通过实验验证,光纤耦合模块可以通过芯径105μm、数值孔径0.22的光纤输出大于110 W的功率,并且亮度达到8.64 MW/(cm^2·sr)。

Base on multiple single emitters using spatial beam combining as well as fiber coupling techniques,a high-power and high-brightness fiber-coupled laser-diode module with 9 single semiconductor laser emitters at 915 nm inside was fabricated.It was demonstrated both by ZEMAX software simulation and experiment.The module can pro-duce more than 110 W output power from an optical fiber with core diameter of 105μm and numerical aperture（NA） of 0.22 with equalizing brightness of 8.64 MW/（cm^2·sr）.The compactness,higher effciency,and lower cost production of the diode are available through this technique,and much wider applications of fiber-coupled laser-diodes are anticipated.
