Abstract

High-power semiconductor lasers could be used as pumping sources for solid-state lasers, fiber lasers, Raman lasers, and for material processing and medicine applications, etc. In this work, we discover a new broad-area waveguide structure that could result in high output power with diffraction-limited beam. The structure has the broad-area waveguide similar to the conventional broad-area laser diodes, but the waveguide is aligned at 7/spl deg/ from the normal of the cleaved facets. The waveguide is very broad. The width is 100 μm. Its length is 1.5 mm.
