摘要
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105 μm、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/(cm2·sr)。
Abstract
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 produce more than 110 W output power from an optical fiber with core diameter of 105 μm and numerical aperture (NA) of 0.22 with equalizing brightness of 8.64 MW/(cm2·sr). The compactness, higher efficiency, and lower cost production of the diode are available through this technique, and much wider applications of fiber-coupled laser-diodes are anticipated.
