57AbstractABDie vorliegende Erfindung betrifft einen Breitstreifen-Diodenlaser (engl. „broad-area dioden laser", BAL) mit integriertem p-n-Tunnelübergang. Insbesondere betrifft die vorliegende Erfindung einen Hochleistungs-Breitstreifen-Diodenlaser bei dem zur Verbesserung der Strahlqualität und zur Reduzierung des thermischen Widerstands ein in Sperrrichtung vorgespannter p-n-Tunnelübergang in das Schichtsystem des Diodenlaser integriert ist. Eine erfindungsgemäße Laserdiode umfasst eine zwischen einem n-dotierten Halbleitermaterial (10, 12, 14) und einem p-dotierten Halbleitermaterial (30, 32, 34) ausgebildete aktive Schicht (20), wobei die aktive Schicht (20) entlang einer Längsachse eine aktive Zone zur Erzeugung elektromagnetischer Strahlung ausbildet; wobei zwischen einem aufliegenden p-seitigen Metallkontakt (52) und dem p-dotierten Halbleitermaterial (30, 32, 34) mindestens eine n-dotierte Zwischenschicht (50, 54) angeordnet ist, wobei in der mindestens einen n-dotierten Zwischenschicht (50, 54) im Bereich oberhalb der aktiven Zone ein unmittelbar an das p-dotierte Halbleitermaterial (30, 32, 34) angrenzender p-n- Tunnelübergang (40) ausgebildet ist.
