The generation of harmonics from solid targets irradiated with relativistic laser pulses constitutes a route towards the generation of intense XUV attosecond pulses. In contrast to the generation of high harmonics from gaseous targets the process using surfaces is scalable to arbitrarily high driver laser intensities giving thus rise to the possibility of exploiting the new higher power laser systems becoming available. It appears now quite feasible to generate very intense attosecond pulses with conversion efficiencies as high as a few percent.
In this talk we present both theoretical and experimantal results of our work towards the spectral, spatial and temporal characterization of high order harmonics generated from solid fused silica targets with the ATLAS 45fs 25TW laser system at the MPQ.
