[Abstract]:In view of the far-field characteristics of high-power pulsed semiconductor lasers and the requirement of laser guidance for laser power density and laser spot uniformity, a multi-aperture spatial coupling scheme is presented and its advantages are analyzed theoretically. According to the polarization characteristics of high power semiconductor laser with nano-stacked chip, polarization beam combination of two high power semiconductor array lasers is studied based on the principle of polarization multiplexing. The experimental results show that the output power of the system is almost 2 times that of a single laser after polarization coupling, and the multi-aperture coupling and polarization coupling can meet the requirements of remote control guidance spot.
