The combined effect of femtosecond laser pulse shaping and self-phase modulation — •Fedor Mayorov, Andreas Assion, Matthias Wollenhaupt, Andreas Präkelt, Marc Winter, and Thomas Baumert — University of Kassel, Institute of Physics and Center for Interdisciplinary Nanostructure Science and Technology (CINSaT), Heinrhich-Plett Str. 40, D-34132 Kassel, Germany

Self-phase modulation is used in different nonlinear optical experiments, such as nonlinear femtosecond laser pulse compression techniques and transient absorption spectroscopy. We used a spatial light modulator to create a spectral hole in the spectrum of femtosecond laser pulse. Spectral redistribution effects, due to self-phase modulation were studied close and below the threshold energies. Z-scans were performed in order to demonstrate the surface sensitivity of this technique. This may have applications in the field of material processing and microscopy.
