Radiation Intensity of a Charged Particle in the Field of a Polarization-Modulated Electromagnetic Wave
摘要
A classical theory of radiation from a relativistic charged particle linearly accelerated by a high-intensity laser pulse with modulated polarization is developed via solving the equation of motion of a charge in the electromagnetic wave field. The formulas for calculating the spectral and angular characteristics of radiation, namely, the radiation intensity of a particle and its phase- and phase-angle distributions are obtained. The graphs of dependence of the radiation characteristics on the modulation coefficient are constructed.
