On acceleration of charged particles in intensity minima of laser fields

Using Klíma-Bogoliubov-Zubarev method, the acceleration of charged particles (electrons) in moving intensity minima of interference laser fields is investigated. The electromagnetic field intensity threshold for a prospective slipping-through of the particle through the potential barrier is found both analytically and numerically. Millimetre and submillimetre electromagnetic waves should be emitted because of forced electron oscillations in potential wells.This work has been initiated by gratefully acknowledged discussions with Professor H.
