Effiziente Hochleistungs-Diodenlaser

Wissenschaftler des Ferdinand-Braun-Instituts verdoppeln die Leistung von DFB-Lasern / Dies erschließt neue Anwendungen in leistungsstarken Systemen

(PresseBox) (Berlin, )
Wissenschaftler des Ferdinand-Braun-Instituts, Leibniz-Institut für Höchstfrequenztechnik (FBH) haben leistungsstarke, hocheffiziente Distributed Feedback (DFB)-Laser mit einer Wellen­länge von 976 Nanometern entwickelt. Die optische Leistung konnte dabei mit 11 Watt aus einem 90 Mikrometer breiten Streifen gegenüber den leistungsstärksten bisher verfügbaren DFB-Lasern mehr als verdoppelt werden. Entscheidend ist, dass die Laser zugleich eine hohe Konversionseffizienz besitzen: Der Anteil an elektrischer Energie, der in Licht umgewandelt wird, beträgt bis zu 58 Prozent. "Durch die Kombination von hoher Leistung und hoher Effizienz erschließen sich für die DFB-Laser neue Anwendungsgebiete, wie das Pumpen von Faser- und Festkörperlasern oder die Materialbearbeitung", sagt Dr. Paul Crump vom EEW.
