KW-output High Beam Quality Diode Laser Array source
With the advantages of small volume, light weight, high efficiency and long lifespan, diode laser has been widely applied to industrial processing. Presently, for laser used as processing light source needs to amount to dozens of KW per cm2 of power density, how to increase power output and get smaller light spot for diode laser becomes a key problem. It is introduced that by designing beam shaping by ourselves and making use of optical system for beam blooming and focusing, 808nm laser array composed of 20 bars eventually achieves the 1001.5w power output, coupling efficiency at 90％, 1x1mm2 of light spot through experiments, which enables diode laser to be directly applied to cladding, welding and so on.
