Abstract :
CW output power in excess of 2 watts was obtained from an InGaAs DBR MQW VCSEL array. This is the highest CW power achieved from a monolithic VCSEL structure to date. We report the performance of several VCSEL arrays. By active cooling of the laser arrays, we were able to repeatedly generate >2 W CW output power at 940 nm. This is the highest CW output power achieved from a monolithic VCSEL array to date.
