Relativistic nonlinear optics of free electrons in laser-driven plasmas

Research output: Contribution to conferencePaper

Abstract

We discuss recent experimental results obtained in a new regime in the interactions of light with matter enabled by table-top lasers capable of delivering ultra-short (femtosecond) duration pulses, focusable to intensities exceeding one exawatt per square centimeter (1018 W/cm2). Novel nonlinear optical phenomena, such as relativistic self-focusing, self-modulation and harmonic generation by Thomson scattering, occur when electrons at the laser focus become relativistic in a single optical cycle. Collimated beams of megaelectronvolt-energy electrons and ions result from enormous space-charge fields (exceeding 1 gigaelectronvolt/cm), driven by gigabar light pressure.
