Transmission of parametrically polarization shaped pulses through a hollow core photonic crystal fiber

Date Mi, 03.12.2014 - Mi, 03.12.2014
Time 11.15
Speaker Dr. Georg Achazi, Institute for Experimental Physics, Freie Universität Berlin, Berlin, Germany
Location Universität Bern, Institut für Angewandte Physik, Gebäude exakte Wissenschaften, Hörsaal B78, Sidlerstrasse 5, 3012 Bern
Program In this talk a method for ultrafast polarization pulse shaping through a micro structured hollow core photonic crystal fiber is presented. The pulses are shaped in pulse sequences in which the energy, distance, phases, and chirps as well as the state of polarization of each individual sub-pulse can be independently controlled. The application of these pulses for coherent control is demonstrated for feedback loop optimization of the multi-photon ionization of potassium dimers and the posiblity to reconstruct the pulse shape by reflecting the pulses back through the fiber is shown.
