摘要：

The paper reports the development of the 915 nm laser module (LM) based on high-power single-emitter InGaAs/AlGaAs laser diodes (LDs). The main options to increase the output LM power as compared to the previous sample were considered. The optical system was designed for coupling the beams into a silica-silica fiber with a core of 200 mu m in diameter and a numerical aperture of 0.22. The maximum reached CW output power was 368 W at a nominal current of 22 A and thermal stabilization temperature of 20 degrees, the total LM efficiency of 47%.
