Abstract

High power semiconductor lasers have applications in spectroscopy, telecommumcations, manufacturing and materials processing, medicine, free space commtmication or energy transfer. Powers of ~1 W or more require large apertures ~100 µm which lead to high order transverse modes, filamentation and spatio-temporal instabilities, all of which degrade spatial coherence and therefore brightness.
