High power coupled multiple stripe quantum well injection lasers

Abstract

Operation of a coupled multiple stripe quantum well injection laser array is described. The device emits up to 400 mW of continuous output power and 2.1 W of peak pulsed (75 ns) output power from an uncoated mirror facet. Its far-field pattern is invariant to over three times threshold, and over 140 mW cw are coupled into a 100-μm core 0.3-numerical aperture (N.A.) optical fiber.
