Abstract

Proton emission from 60-fs, 200-mJ high-repetition-rate tabletop-laser pulses interacting with solid targets was studied. A maximum proton energy of 1.5 MeV was measured for Mylar targets of thickness 20-40 μm. Results showed a maximum energy of 950 keV for 12μm for aluminum targets, and 850 keV for 12.5μm for copper targets.
