Abstract

The work was dedicated to the laser modules for the spectral range of 975 nm based on single laser diodes with fiber output to be designed and manufactured. The installation of an optical system for the seven laser diodes radiation input into a silica-silica fiber with a core diameter of 105 μm and a numerical aperture of 0.15 has been carried out while investigating their power and spectral characteristics. The maximum output power of the laser module was 65 W in CW operation at a nominal current of 12 A and a thermal stabilization temperature of 25°C, the total efficiency of the laser module was 43%, and the brightness of the laser module amounted to 10.6 MW/(cm2 sr).
