Experimental study on high brightness blue diode laser fiber coupling
Based on the advantages of diode laser, such as high efficiency and high integration, blue diode laser source can be widely used in highly-reflective and highly conductive materials processing. This paper introduces a high power high brightness blue diode laser fiber coupling module based on 3×9 single emitter diode laser array, which can realize 75 W single polarization 450 nm diode laser output from 100 μm 0.2 NA fiber. Polarization beam combining can also be used to further improve the fiber coupling blue diode laser power.
