Nonresonant Compton scattering in an intense pulsed laser field

The influence of an intense pulsed light wave on nonresonant scattering of a photon by an electron is investigated in the approximation when the pulse width is considerably greater than the characteristic time of wave oscillation. The partial differential cross-sections for different numbers of absorption (emission) wave photons are analyzed for a range of external field intensities I similar to 10(17) W cm(-2). The general relativistic expression for the nonresonant cross-section of laser-modified Compton scattering summed over all possible partial processes is derived. It is shown that for nonrelativistic energies the pulse character of the external field significantly affects the process.
