Light interaction with charged particles

AI Thread Summary
When a laser interacts with charged particles, the outcome depends on the type of light and the charged particles involved. Photons can be absorbed, leading to a decrease in laser intensity, or they may be scattered, resulting in phenomena such as redshift. The interaction mechanisms vary significantly between radio frequency (RF) fields used in particle accelerators and high-powered, short-wavelength lasers. High-energy lasers can induce complex interactions, including Compton scattering. Understanding these interactions is crucial for advancements in particle acceleration technologies.

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.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
