Abstract

The invention discloses an ultra wide band high-power terahertz radiation source. The ultra wide band high-power terahertz radiation source comprises a negative electrode, a slow wave structure, an energy output coupler and a terminal adapter, wherein the energy output coupler is a three-port element; band-shaped electron beams generated by the negative electrode enter the energy output coupler from a band-shaped electro injecting port, and then the electron beams are output to the slow wave structure from a connecting port of the slow wave structure to generate a terahertz radiation source signal; after the terahertz radiation source signal is reflected in the terminal adapter, the terahertz radiation source signal passes through the slow wave structure to return to the energy output coupler; and finally the terahertz radiation source signal is output through a terahertz radiation source signal output port. The terahertz radiation source has the following characteristics that the terahertz radiation source has ultra wide tuning operation and watt-magnitude high power; the start-oscillation condition can be well satisfied; the requirement on the current density of the electron beams is relatively low; the terahertz radiation source is stable in output signals and pure in frequency spectrum; and the terahertz radiation source is low in operating voltage, small in size, easy to process and assemble, and the like.

Description

technical field [0001] The invention belongs to the technical field of vacuum electronics, and more specifically relates to an ultra-broadband high-power terahertz radiation source. This invention is based on the applicant's application for an invention patent with the application number 201510965016.0 and the title "An ultra-wideband quasi-open slow wave structure" filed on December 21, 2015. Background technique [0002] Terahertz waves refer to electromagnetic waves with a frequency in the range of 0.1-10THz (wavelength 0.03-3mm). Since this wave band has the characteristics of both millimeter waves and infrared light, it combines the advantages of millimeter waves and infrared light. Terahertz technology has broad application prospects in high-speed data transmission, high-precision imaging radar, chemical or biological map analysis, biomedical diagnosis, and material analysis. The generation of terahertz waves is the basis for the application of terahertz technology. ...
