Abstract :
High brightness semiconductor lasers have many applications. The main difficulty associated with high brightness is that, because of COD, high power requires a large aperture. Large apertures result in high order transverse modes, filamentation and spatio-temporal instabilities, all of which degrade spatial coherence and therefore brightness
