Abstract

The generation of dense relativistic electron layers by high-contrast few-cycle multi-TW laser pulses is described and their use as relativistic mirrors to produce ultra-bright attosecond light pulses. The method is illustrated in Fig. 1. Nanometer-thick foils are irradiated to blow out all electrons. They move as dense layers with γ-factors of 10 -100 over distances of a few laser wavelengths without substantial expansion. This is shown by 1D and 2D PIC simulation. These layers are dense enough for coherent Thomson backscattering of counter-propagating probe light. Though they are typically transparent to the scattered light, the reflection occurs coherently. As a major new result, we report the fraction of reflected light energy in 1D geometry. The reflected probe light is compressed and upshifted in frequency by factors 4γ2. This leads to single attosecond pulses in the VUV and X-ray regime. The brightness of these pulses is estimated.
