Abstract

We report a method of scaling the spatial brightness from commercial off-the-shelf diode laser stacks through wavelength beam combining, by use of a linearly wavelength-chirped volume Bragg grating (VBG). Using a three-bar commercial stack of broad-area lasers and a VBG, we demonstrate 89.5Wcw of beam-combined output with a beam-combining efficiency of 75%. The output beam has a propagation factor M226 on the slow axis and M221 on the fast axis. This corresponds to a brightness of 20MWcm2sr. To our knowledge, this is the highest brightness broad-area diode laser system. We achieve 81% coupling efficiency into a 100μm, 0.22N.A. fiber.
