Paper Abstract

1407_70It is shown that the acceleration by net inverse bremsstrahlung of a laser light is a classical phenomenon in which high-energy electrons, whose momenta and energies are modulated by the laser light, obey strictly the momentum and energy conservation laws and the time-reversal invariance of the transition probability. Net inverse bremsstrahlung acceleration of high-energy electrons traveling in a strong laser light and an electrostatic wave propagating in an oblique direction with respect to the laser light is investigated by using the relativistic quantum-kinetics based on the Dirac equation. The quantum kinetics treats the classical phenomenon exhibited by high-energy electrons through the correspondence principle. The dc force in the laser light direction by the net inverse bremsstrahlung is independent of the spread of the electron beam energy, and increases with the electron beam energy. Also, the dc force increases with the laser intensity if the potential amplitude of the laser wave is smaller than the electron rest energy.
