Paper Abstract

New results from the interaction of ultra short laser pulses with ionization fronts are presented. The frequency up- shifts, due to photon acceleration, were obtained in a co- and counter propagation scheme. The different levels of frequency up-shift observed give us not only the overall plasma density but also information about the fine structure of the ionization font. The correlation between the interaction lengths for co- and counter-propagation, with the longitudinal and transverse dimensions of the ionization front is also discussed. Those result clearly show the capability of using photon acceleration phenomena to fully characterize a relativistic ionization front.
