In the proposed project, we will design, fabricate, and demonstrate a prototype UVA laser module with greater than 0.5W output power. The laser source will consist of a semiconductor laser array that has been coherently combined using a Self-Fourier (SF) cavity. The laser output will be a diffraction-limited beam with an M2 less than 1.2. The results of this project will demonstrate a clear path towards realization of a 3W UVA semiconductor laser array with good beam quality.
