Abstract

We propose an efficient coherent power scaling scheme, the multichip vertical-external-cavity surfaceemitting laser (VECSEL), in which the waste heat generated in the active region is distributed on multi- VECSEL chips such that the pump level at the thermal rollover is significantly increased. The advantages of this laser are discussed, and the development and demonstration of a two-chip VECSEL operating around 970 nm with over 19 W of output power is presented.
