Abstract

We present results on plasma formation in porous silicon (cluster like solid with mean cluster size of 3 nm, mean density 0.1 - 0.2 of crystalline silicon) by femtosecond laser pulses at intensity above 10 TW/cm². We deduced hot electron temperature as high as 8 keV and fast ions of at least 2 MeV energy.
