High brightness is a major issue in most high-power diode laser applications. The brightness of a laser diode primarily depends on the optical power and the product of beam-quality factors in x- and y-direction, i.e. M2xx M2y. Even though there are many broad-area laser diodes which show an impressive brightness, all emitters lack a symmetric beam quality. In the direction perpendicular to the laser junction, the fast axis, the beam quality is perfect, showing an M2y-value of 1. Parallel to the… Expand
Beam shaping of a broad-area laser diode using 3D integrated optics.
TLDR
This Letter presents a 3D integrated optics approach to shape the output of a broad-area laser diode with photonic chip-based approach that results in a 13× higher beam quality and 7× greater brightness. Expand
