Patent number: 11474414Abstract: A technique to generate terahertz radiation is disclosed, where a pump beam (12) is coupled into an optical element (50) made of a medium with non-linear optical properties having plane-parallel front and rear boundary surfaces (51, 52), wherein the pump beam (12) is split into a set of partial pump beams (121) by reflection and/or diffraction on a periodic relief structure (53) of said optical element (50). The partial pump beams travel along a direction at an angle ? that satisfies the velocity matching condition of vp,cs cos(?)=vTHz,f within the given medium, where vp,cs is the group velocity of the pump beam, vTHz,f is the phase velocity of the terahertz radiation and the speed a planar envelope (212) travels toward the front boundary surface (51) of the optical element (50), and angle ? is the angle formed by the pulse front envelope and the phase front of the pump beam.Type: GrantFiled: October 31, 2019Date of Patent: October 18, 2022Assignee: PÉCSI TUDOMÁNYEGYETEMInventors: János Hebling, Gábor Almási, László Pálfalvi, György Tóth
