Abstract

We present a technology for achieving a significant line narrowing (by approximately an order of magnitude) and stabilization of the emission wavelength of multimode high-power laser diodes and arrays. This volume Bragg grating technology also can achieve a significant reduction in the slow axis divergence of a broad-area laser diode simultaneously with spectral line narrowing.
