Femtosecond Spectrostroscopic Ellipsometry — •Shirly Espinoza — ELI Beamlines, Institute of Physics, Czech Academy of Science, Prague, Czech Republic

The current status of a versatile experimental platform dedicated to ultrafast pump-probe ellipsometry with time resolution about 100 fs will be presented. The setup measures the ellipsometric spectra in the range 350-750 nm. The monochromatic pump beam can be chosen from 350 nm to 2 um. This setup give information of ultrafast changes on the optical properties of the materials forming a thin film. Recent results and ideas for expansion of the capabilities of the setup will be presented for discussion.
