Enhanced laser intensity and ion acceleration due to self-focusing in relativistically transparent ultrathin targets

Laser-driven proton acceleration from ultrathin foils is investigated experimentally using f/3 and f/1 focusing. Higher energies achieved with f/3 are shown via simulations to result from self-focusing of the laser light in expanding foils that become relativistically transparent, enhancing the inte...
