Description
We propose a uniform formulation to calculate photon emission processes from a charged scalar field or spinor field under the strong laser field. One photon emission from a charged particle, which is forbidden in the vacuum, can be observed in the strong EM field, for example, SLAC E-144 experiment (1997). The process is expressed as non-linear Compton scattering, which means the number of incident photons is 2, 3 or more. But in the short pulse strong laser field, the expression must be changed because the laser field includes various frequency photons.
In this presentation, we show that not integer but real number photons interact with a charged particle under short pulse laser field, how to calculate these processes with non-linear QED and some numerical results.
