Combining developments in high-power (/spl sim/100 W) laser diode arrays and high heat flux (kW/cm/sup 2/) water-cooled Cu-'mini-channel' heatsinks, we demonstrate record average power density operation of diode laser stacks. Using advanced die attachment, record CW power levels of 180 W and 108 W has been demonstrated at 915 nm & 808 nm, respectively, from 1 cm wide laser arrays on such heatsinks.
