The coherence properties of high power semiconductor lasers with a modified transverse current profile were analyzed. Current profiling can be implemented in vertical cavity lasers with proton implementation or imhomogeneous optical pumping. The analysis of beam propagation demonstrated that the device emits on a single transverse mode which can be focused into a single-mode fiber.
