Abstract
Um ein Halbleiterlasersystem mit mehreren einen Laseroszillator umfassenden Halbleiterlasereinheiten, mit einem Kopplungselement, welches die aus der jeweiligen Halbleiterlasereinheit austretende Laserstrahlung in die jeweilige lichtleitende Faser einkoppelt, und mit einem die Fasern umfassenden Faserbündel, aus dem eine durch die Summe der jeweils von den Halbleiterlasereinheiten erzeugten kohärenten Laserstrahlung gebildete Gesamtlaserstrahlung austritt, und mit einer Steuerung, mit welcher die Leistung jeder einzelnen Halbleiterlasereinheit definiert steuerbar ist, wobei die Steuerung eine Bestrahlung unterschiedlicher Flächenelemente der Zielfläche mit einzeln für jedes Flächenelement definierbarer Intensität vorgebbar ist, derart zu verbessern, daß mit diesem komplexe Bestrahlungsaufgaben in einfacher und möglichst effektiver Art und Weise durchführbar sind, wird vorgeschlagen, daß die Fasern Monomodefasern sind, daß jede der Halbleiterlasereinheiten im transversalen Grundmode arbeitet und daß die Einkopplung der Laserstrahlung in jede Monomodefaser beugungsbegrenzt erfolgt.
