Light interaction with charged particles

  1. Jan 15, 2016 #1
    Does anybody know what happens when say a laser accelerates charged particles?

    Do photons get absorbed and the intensity of the laser drops, or do they get absorbed and scattered and there's a redshift of the photon etc

    Please note that "light", as in electromagnetic wave, interacts with charge particles very often. We use rf in accelerating structures to accelerate charged particles in particle accelerators. That is how many, if not most, major particle accelerators work!

    How they interact, and the nature of the interaction depends very much on not only the charge particles, but also the nature of this light. Interaction rf is different than interaction with high-powered, short wavelength laser source. The latter might induce a bunch of interactions such as compton scattering, etc. There's a zoo of this.
