Light interaction with charged particles

Click For Summary
SUMMARY

The discussion focuses on the interaction between lasers and charged particles, specifically how photons behave when they accelerate these particles. It is established that the interaction varies significantly based on the type of light used, such as radio frequency (RF) versus high-powered, short-wavelength lasers. Key interactions include photon absorption, scattering, and potential redshift effects. The conversation highlights the complexity of these interactions, particularly in the context of particle accelerators.

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.
