Abstract:
A method of producing coherent electromagnetic radiation, comprising the steps of:(i) providing a primary beam of positively ionized atoms and electrons moving along a first specified path,(ii) providing a secondary beam of electrons and ionized atoms moving along a second specified path,(iii) providing a means to deflect electrons of a section of the secondary beam towards the primary beam to be made to overlap with a section of the primary beam, and(iv) providing a means to progressively vary the section of the secondary beam being deflected toward the primary beam so that the section of the primary beam overlapping with a section of the secondary beam shall vary, and the said varied section of the primary beam overlapping with a section of the secondary beam advances along the length of the primary beam at the speed of photons in the medium of the primary beam.
