The chirped-pulse amplification technique has opened up a completely new scenario in laser-matter interaction. Radiation intensities in excess of 1018W/cm2, leading to relativistic electron motion in the laser field, induce phenomena (sometimes very spectacular) concerning laser pulse propagation, particle acceleration and generation of energetic electromagnetic radiation. The suitable utilization of such phenomena allows for several applications, including the fast ignition of an inertially confined fusion target, the production of energetic particles (electrons, protons, ions and positrons), and X-gamma rays for medical diagnostics and therapy.

Abstract
The chirped-pulse amplification technique has opened up a completely new scenario in laser-matter interaction. Radiation intensities in excess of 1018W/cm2, leading to relativistic electron motion in the laser field, induce phenomena (sometimes very spectacular) concerning laser pulse propagation, particle acceleration and generation of energetic electromagnetic radiation. The suitable utilization of such phenomena allows for several applications, including the fast ignition of an inertially confined fusion target, the production of energetic particles (electrons, protons, ions and positrons), and X-gamma rays for medical diagnostics and therapy.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
