Characterization and optimization of a Ti:Sapphire laser beam profile

This project aims at the optimization of the spatial properties of ultrashort laser pulses generated in a Ti:Sapphire laser system. Applying a recently proposed simple experimental approach we intend to set up a novel type of spatial filter for improving the wave front of the laser pulses. The work includes a careful characterization of the current and - after installation of the new spatial filter - the resulting wave fronts. Simulations also may be included into this project.

 

Development of a detector for THz and NIR light pulses

Performing pump-probe experiments using ultrafast light pulses of different wavelength requires sophisticated tools to be able to overlap all involved light pulses in space and time. In particular when non-visible radiation is used, special techniques have to be applied. The planned work should set up and test a new type of detection scheme based on a semiconductor device that is capable of detecting the overlap of a THz and a NIR laser pulse on an ultrashort time-scale.

 

Pump-probe experiments using DUV and VUV radiation

Based on an industrial laser system we operate a table-top light source generating ultrashort light pulses at 85nm wavelength by frequency conversion of the fourth harmonic (257nm) of the laser fundamental in a static gas cell. Recently, an optical setup for the transport of the DUV and laser radiation to the interaction region, where pump-probe studies on gaseous samples will be carried out, was realized. In a next step, an experimental chamber hosting a spectrometer/detector for either electrons or ions created by the light-matter interaction needs to be set up. This project can be carried out within the scope of a Bachelor or Master thesis.
