Design and realization of high power semiconductor lasers

Abstract

In this paper we present latest developments on devices at 800–1020nm with a peak wall plug efficiency 68% at 120W at 980nm. New applications are now driving the need for other wavelengths such as 790nm and 1400–1600nm. By using non wavelength specific build standards we show how high power and brightness can also be provided for this extended wavelength range.
