In the previous chapter a modulation of the XUV absorptivity by up to \(10\,\%\) in the presence of the strong field is detected. This modification is the signature of a severe field induced perturbation of the electronic system which should also affect other experimental observables. Once the strong field dynamics are triggered they are assumed to affect the penetration of the pump field into the medium. To investigate this phenomena the reflectivity of the few-cycle laser pulse is recorded as a function of its amplitude with femtosecond resolution.
