120 W CW output power from monolithic AlGaAs (800 nm) laser diode array mounted on diamond heatsink

Continuous-wave output power levels of 120 W at 2 o C and 100 W at room temperature are reported from 1 cm wide monolithic AlGaAs (800 nm) laser diode arrays with a 7200 μm total aperture width by using diamond heatsinks. Additionally, 25 W CW operation up to 90 o C has been demonstrated
