【 摘 要 】

When an intense relativistic short laser pulse incident on an optically polished surface, it generates a high density plasma that acts as a relativistic plasma mirror. As this mirror reflects the intense laser field, its space time characterization changes due to high nonlinear response of the field. This lead to the phase variation both temporally and spatially that could affect the generation of high harmonics of the laser and attosecond pulses. The present theoretical study address the issues of the intensity dependent space-time characteristics on the generation of attosecond pulses from relativistic plasma mirror.
