Innovation in Broad-Area Diode Laser Array Architecture: Coupling Grating-Confined Zigzag Modes for High Power, High Brightness Applications

Abstract

This project aims to demonstrate coherent beam combining in a new, completely integrated approach to edge-emitting, high power semiconductor laser emitters and arrays. We have successfully demonstrated integrated mode control and coherent beam combining of high power, broad area lasers through transverse Bragg diffraction. The proposed concept has many advantages over traditional beam combining methods based on discrete and bulky optical components. We have shown that the proposed approach can effectively realize the single mode operation of broad-area diode lasers and coherently combine these angled-grating lasers with high efficiency.
