Abstract

Blue semiconductor lasers have broad application prospects in fields such as material processing, underwater communication, and ocean exploration due to their unique wavelength advantages. At present, the power of blue light single tube LDs is relatively low. By using incoherent laser beam combining technology and fiber coupling technology, multiple blue light LDs can be synthesized into a high-power and high uniformity laser, meeting a wider range of application needs. This article designs a 100W level blue light LD fiber coupling module, which uses 32 single tubes with a power of 5W LDs. Through spatial and polarization beam combining design, it is focused and coupled into 105 μm/NA0.22 optical fiber. After simulation with Zemax software, a 138.7 W high brightness blue laser was obtained, with a fiber coupling efficiency of 91.48%. A dual axial flow fan air-cooled heat dissipation structure has been designed. After simulation with Ansys Icepak software, the maximum temperature of the laser module is 35.1 °C, and it can continuously output light for operation.
