Effizienz-Weltrekord bei 808 nm im Labor erreicht

Neue Laserbarrengeneration in den Startlöchern

(PresseBox) (Regensburg, )
Mit 64 % Effizienz bei 120 W optischer Ausgangsleistung markieren Laserbar-ren mit 808 nm Wellenlänge einen neuen Weltrekord. Osram Opto Semiconduc-tors hat dieses Ergebnis gemeinsam mit dem Laserspezialisten DILAS - im Rahmen des Forschungsverbundprojekts „BRILASI“ - erreicht. Die Werte ent-standen unter Laborbedingungen bei Raumtemperatur und berücksichtigen bereits die Verlustleistungen des elektrischen Systems.

Die Laserbarren mit Leistungs- und Effizienzsteigerung gelten als Prototypen für eine neue Generation von Diodenlasern. Mit Leistungen von 120 W wird sich das Leis-tungsniveau gegenüber heutigen Standardwerten bei 808 nm Wellenlänge (60 W, 55% Effizienz) in Zukunft annähernd verdoppeln. Gleichzeitig wird die Effizienz um etwa 10% steigen.
