Relativistic laser-plasmas: novel sources of x-rays and particle beams — •Alexander Pukhov — Institute for Theoretical Physics I, Uni-Duesseldorf

Laser plasma becomes relativistic at intensities I well above 10^18 W/cm^2. One of the main applications for relativistic laser plasmas is the high-gradient particle acceleration and new table-top sources of short wavelength radiation. The main breakthrough happened in the last two years as a number of experimental groups reported monoenergetic electron beams from laser plasmas reaching GeV energies. These beams have been accelerated in the Bubble regime [Pukhov, Meyer-ter-Vehn, Applied Phys. B74, p.355 (2002)]. The main numerical tool to study the relativistic laser plasmas are particle-in-cell simulations. In the ultra-relativistic regime, I>>10^18 W/cm2, the S-similarity theory [Pukhov, Gordienko, Phil. Trans. R. Soc. A364, p. 623 (2006)] helps to scale experimental results.
