Abstract
Provided is a linearly polarized ultra-short terahertz wave generating device which has a parabolic barrel mirror installed at one side of a multiple thin film, to generate an ultra-short terahertz wave having single linear-polarized light and uniformly formed output distribution.
Claims12
A device for generating a linearly polarized ultra-short terahertz wave, comprising:
- a parabolic mirror barrel configured to extend in one direction, and having a parabolic mirror concaved on an upper surface thereof, with an end surface of the parabolic mirror perpendicular to the extending direction forming a parabola;
- a plurality of thin films configured to be arranged on the parabolic mirror in the extending direction of the parabolic mirror barrel and having at least some areas thereof disposed to overlap each other;
- and
- an electron accelerator configured to generate an electron beam passing through the plurality of thin films,
- wherein spacing spaces are formed between some areas in which the plurality of thin films overlap each other, and when the electron beam passes through the plurality of thin films and the spacing spaces, a linearly polarized terahertz wave is generated between the spacing spaces.
