Abstract |
To investigate the device which is capable of generate and amplify a
coherent electromagnetic radiation in the millimeter and submillimeter
wavelength ranges is extremely important today. In the research under
discussion the model of a plasma-beam superheterodyne free electron laser
(SFEL) is the following. Plasma is located in the longitudinal focusing
magnetic field with strength H0. Relativistic electron beam is injected into
this plasma environment at an angle α with respect to the magnetic field
strength vector. We chose a circularly polarized intense low-frequency
electromagnetic wave as a pump. This wave propagates along the guiding
magnetic field and in the opposite direction to the electron beam. Also we
feed a weak high-frequency circularly polarized electromagnetic wave
(signal wave) into the system. The direction of the wave signal may be
different, so the wave number can either positive or negative. The
parametric resonance between the signal wave and the pump wave results
in excitation of a space-charge wave (SCW). |
