Multi-energy ion implantation from high-intensity laser

The dominant regime in most of experiments on ion acceleration from solid targets is the target normal sheath acceleration (TNSA). It is used in laser-matter interaction for laser intensities ranging approximately between 1016 and 1022 W/cm2 as reported in several publications [1, 2]. Several models and scaling laws have been suggested to predict the maximum ion energy of accelerated ions in the TNSA regime on the basis of the laser and target parameters [3]. A recent study [4] showed the signifi cant acceleration effect observed at laser intensities of the order of 1016 W/cm2. Experimental detection of ions with energy higher than 4 MeV/charge state as well as the generation of multi-MeV electrons and of intense UV and X-ray emission are referred to the TNSA regime applied to thin foils [4]. A few recent publications, despite reporting the high value of laser irradiance required into the TNSA, support the idea that an increase in laser intensity is generated by decreasing the laser foMulti-energy ion implantation from high-intensity laser Mariapompea Cutroneo, Lorenzo Torrisi, Jiri Ullschmied, Roman Dudzak
