Multichannel Quasi-CW Lasers

MCQL lasers feature from 2 to 6 individually programmable flexible fiber delivered optical outputs. These QCW fiber lasers provide peak powers up to 6 kW, pulse energies up to 60 J and average powers up to 500 W per channel. Processing a variety of metals - steel, CuNiSi alloys, aluminum and copper and dissimilar metals - MCQL lasers are an ideal replacement for lamp-pumped lasers in pulsed welding applications such as welding stamped parts and electrical connectors. With high beam quality, small spot sizes and low heat input resulting in better welding quality, MCQL lasers are order of magnitude more productive, electrically efficient, virtually maintenance-free, and have much smaller footprint than legacy lasers.
