Abstract

Most of the potential applications of high power laser diode bars and stacks need special beam transformation systems in order to create a much more symmetric output beam. We present a novel concept for single emitted beam reconfiguration of high power laser diode bars, which uses different types of microoptical components. A very compact and efficient beam shaping system has been built upon the base of this concept, forming a nearly circular output beam with minimum brightness reduction compared to the laser diode output radiation.
