摘要

We investigate the harmonics generation from a pure dielectric target when submitted to laser intensities in the 10~(18)W/cm~2. We demonstrate the negative influence of the prepulses and ASE by addressing the direct comparison of the harmonic spectra with and without the introduction of a perfectly controlled plasma mirror system. Harmonics up to the 20th of the fundamental of the Ti-Sa laser are clearly visible in a situation free of any plasma expansion.
