  • Coherent counter-streaming electrostatic wave raman interaction system utilizing opposing electron beams for the production of coherent microwaves in plasmas
    Patent number: 4059813
    Abstract: The generation of controlled, electromagnetic, coherent, microwave radiation from a warm, uniform plasma at approximately twice the electron plasma frequency by means of two oppositely directed streams of high energy electrons and the coupling of the resulting coherent, electromagnetic radiation from a cavity resonator into external circuitry, wherein the two opposing streams of high energy electrons directed into the warm, uniform plasma result in a conversion of electron beam and plasma energies into transverse electromagnetic radiation from 10 to 100 times that which is possible with a single electron beam-plasma system.
    Type: Grant
    Filed: January 12, 1977
    Date of Patent: November 22, 1977
    Inventors: Clare C. Leiby, Jr., Balram Prasad
  • Coherent generation of microwaves by stimulated Raman emissions
    Patent number: 3944946
    Abstract: The generation of controlled, electromagnetic, coherent, microwave radiation from a warm, uniform plasma at approximately twice the plasma frequency by means of a source of high energy electrons being directed into a plasma and coupling the resultant energy from a cavity resonator to external circuitry.
