Abstract

We report on experimental investigations of proton acceleration from thin foil targets irradiated with ultra-short (∼50 fs), high contrast (∼10¹⁰) and ultra-intense (up to 10²¹ W/cm ²) laser pulses. These measurements provided for the first time the opportunity to extend the scaling laws for the acceleration process in the ultra-short regime beyond the 10²⁰ W/cm² threshold. The scaling of accelerated proton energies was investigated by varying the thickness of Al targets (down to 50 nm) under 35° angle of laser incidence and with p-polarised light.
