Abstract
A device ( ) for producing high frequency radiation using a source of elliptically polarized radiation is disclosed based on: irradiating a frequency multiplication medium having a screw axis ( ) symmetry of approximate Nth order symmetry, oriented so that said elliptically polarized radiation propagates in parallel to the screw axis ( ). Also, a method for producing high frequency radiation is disclosed based on irradiating a frequency multiplication medium having a screw axis ( ) of approximate Nth order symmetry with elliptically polarized radiation so that the elliptically polarized radiation propagates in parallel to the screw axis ( ). Furthermore, a method of producing a beam of high frequency radiation composed of only a limited number of wavelengths is disclosed whereby the intensity of a beam ( ) interacting with a frequency multiplication medium is selected so that only a limited number of wavelengths is emitted.
