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%  11mm2 of light spot through experiments  which enables diode laser to be directly applied to cladding  welding and so on. 2012 IEEE.
