Das Laser Zentrum Hannover e.V. (LZH) hat ein ultra-kompaktes Femtosekunden (fs) Lasersystem hoher Leistung entwickelt, das im Telekommunikationswellenlängen-Bereich um 1,55 µm emittiert. Das auf einem Erbium-Faseroszillator basierende Lasersystem mit einer Pulswiederholrate von 108 MHz hat eine hohe Pulsspitzenleistung von ~ 100 kW bei einer nahezu bandbreitenbegrenzten Pulsdauer kleiner 65 fs. Auf der Basis eines neuartigen Pulsformungsprozesses konnte mit 0,7 Watt eine siebenfach höhere mittlere Ausgangsleistung im Vergleich zu bislang demonstrierten Erbium Faseroszillatoren erreicht werden. Des Weiteren ist dieser Laser der erste, bei dem dieser Pulsformungsprozess ohne die Verwendung von Freistrahl-Komponenten realisiert werden konnte.
