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)。 Nine high-power, high-brightness output optical fiber coupling modules are fabricated by coupling nine single-core semiconductor lasers with a wavelength of 915 nm into the optical fiber with high efficiency through spatial combining technology and optical fiber coupling technology. After simulation with ZEMAX optical software, it is verified through experiments that the fiber coupling module can output more than 110 W power with a fiber diameter of 105 μm and a numerical aperture of 0.22, and the luminance reaches 8.64 MW / (cm ~ 2 · sr).
