The laser-driven accelerators are ultra-compact relativistic ion and proton beam sources that could form the basis for next-generation X-ray light sources and particle accelerators. In this work enhanced yields of protons from laser interactions with solid targets have been investigated. Using a high power laser system (intensity of ~4  1019 W/cm2), hydrogen-doped foils of Au, Cu and Ti have been used as targets to identify the effect of hydrogen implantation on the produced proton beam. From this novel experiment, it has been demonstrated that an enhancement in the proton yield by approximately a factor of 3 is obtained from hydride Au and Cu targets for proton energies of ~3 MeV. Energetic proton beams may be used to some advantage since with conventional accelerators, the monoenergetic beams must be broadened to match the size of the tumour, before being used in therapy
