Ion Acceleration in Multispecies Targets Driven by Intense Laser Radiation Pressure
Ion Acceleration in Multispecies Targets Driven by Intense Laser Radiation Pressure
The acceleration of ions from ultrathin foils has been investigated by using 250 TW, subpicosecond laser pulses, focused to intensities of up to $3\ifmmode\times\else\texttimes\fi{}{10}^{20}\text{ }\text{ }\mathrm{W}\text{ }{\mathrm{cm}}^{\ensuremath{-}2}$. The ion spectra show the appearance of narrow-band features for protons and carbon ions peaked at higher energies (in the $5--10\text{ }\text{ }\mathrm{MeV}/\mathrm{\text{nucleon …
