Abstract

The dependency of the maximum ion energy emitted to rear side of a thin film on laser pulse duration was described by isothermal plasma expansion model, and the maximum proton energy was increased with pulse duration. 1 MeV protons were obtained with laser energy of 30 mJ by optimizing focusing using adaptive optics.
