Advanced high-power pulsed fibre laser systems and their applications
… including high average power femtosecond pulse generation and nonlinear frequency conversion. While the power produced by rare-earth doped fibre lasers operating in continuous-wave has dramatically increased within a few years to exceed the kilowatt level, pulsed fibre sources have been limited …

Influence of the Matrix Environment on the Optical Properties of Incorporated Dye Molecules
… layers in combination with commercial blue light emitting diodes in luminescence conversion devices. It is demonstrated that by optimization of the conversion layer parameters white light generation can be achieved. The devices are characterized by high conversion efficiency and Lambertian …

Pikosekunden-Weißlichterzeugung in mikrostrukturierten Fasern unter Ausnutzung nichtlinear optischer Effekte
Im Rahmen der vorliegenden Arbeit ist es erstmals gelungen, mit einem ps-Pumplaser (10 ps) Weißlicht mit einer spektralen Breite von mehr als einer optischen Oktave in einer mikrostrukturierten Faser (MSF) bei einer Pumpwellenlänge von 1064 nm zu generieren. Es ließ sich, abgesehen von …
