Abstract:
Based on the solution of the equation of motion of a charge in a frequency-modulated electromagnetic field, a classical theory of radiation of a relativistic charged particle linearly accelerated by a high-intensity chirped laser pulse is constructed. This solution was used to study the spectral-angular characteristics of the emission of a charged particle. According to the calculated formulas for the phase and phase-angular distributions of the intensity and power of the radiation of a particle in a modulated field, graphs of the dependence on the value of the modulation coefficient are plotted. Also obtained is the Fourier transform of the electric field strength of the radiation and the spectral density of the radiation of the particle in the case of linear polarization of the wave.
