Laser heterostructures with a broadened MQW waveguide for high-power and sub-ns-laser-pulse-width operation
Design of a structure with QWs distributed in a broadened waveguide layer is presented, which ensures mode selection, preserves the fundamental mode, provides minimum difference of optical confinement factors between QWs for matching the threshold conditions. A peak optical power of 15 W is demonstrated with a pulse width of 80 ps.
