Query: Electro-Optical Radiation of a Charged Particle in a Single Laser Beam
  Field   A peculiar radiation arising as a result of radiation interference of
nonlinear oscillators excited by a monochromatic plane wave field of the
incident particle is described. The radiation properties are determined by the
fact that a phase of each oscillator radiation fields is synchronized by a wave
field, while the radiation itself occurs due to the particle field influence on
the oscillators. The consideration is performed for a thin film with negligible
density effect. It is supposed that the contribution is given only by a
long-wave part of the Weizsacker spectrum for which nonlinear polarization
coefficients of medium are large.
