Abstract

As intense laser sources are constructed around the world, various applications are developed. In the medical field it is foreseen to use laser-driven radiation for cancer diagnostic and radiotherapy. High-power lasers can generate pulsed high dose-rate radiation beams (protons, electrons, X-rays and gamma rays) via laser interactions with primary targets. Experiments have been carried out at various high-power laser research facilities in order to demonstrate the radiobiological effectiveness of laser-driven radiation. In this article, we review the results of a selection of cell irradiation experiments conducted using laser-generated radiation beams.
