  • Abstract
    Surface-emitting lasers with second-order gratings for output coupling have been demonstrated to emit 2.8 W pulsed, with a differential efficiency of 20%. The radiation pattern resulting from the interference of two grating regions indicates coherent operation, and a single longitudinal mode output.
