Techniques in frequency conversion and time-resolved spectroscopy with nonlinear optical processes in the femtosecond regime
Nichtlineare Frequenzumsetzung der niederenergetischen femtosekunden Laserpulsen wurde in den Festkörpermitteln nachgeforscht. Ramanumwandlung im weiss-Licht-freien Regime des impulsiven stimulierten Raman Streuungs wurde erzielt, indem man KGW-Kristall mit den Bessel-Lichtstrahl pumpte. …

Preparation and optimization of low-temperature grown GaAs photomixers
The aim of this work was to design and prepare photomixer devices based on LT GaAs and to optimize them with respect to the maximal output power. Essential part of the photomixer is the MSM photodetector structure. For this reason a major part of the optimization process was done on photodetector …
