Abstract
The problem of the Coulomb explosion of a thin homogeneous foil with light and heavy ions is solved analytically in the context of laser ion acceleration. Spatiotemporal and spectral distributions of the accelerated light ions are obtained. The ions parameters are calculated as functions of the atomic composition of the target. It is shown that, in the interaction between high-power ultrashort high-contrast laser pulses and thin foils with light impurity ions, it is possible to produce accelerated ion bunches that contain a significant fraction of the total number of particles and have a small energy spread (≲10%).
