Nonlinear compton scattering with a multi-petawatt laser producing ultra-bright gamma rays
A team of researchers has successfully demonstrated nonlinear Compton scattering (NCS) between an ultra-relativistic electron beam and an ultrahigh intensity laser pulse using the 4-Petawatt laser. The innovative approach was the usage of only a laser for electron-photon collisions, in which a multi-PW laser is applied both for particle acceleration and for collision (also called an all-optical setup). This achievement represents a significant milestone in strong field physics, in particular strong field quantum electrodynamics (QED), offering new insights into high-energy electron-photon interactions without the need for a traditional mile-long particle accelerator.
