摘要： A terahertz wave generation device is provided with an ultra-short pulse laser light source (3) for generating ultra-short pulse laser light at a single repeating frequency and optical fibers (F1 to F5) for respective transmitting and projecting of the ultra-short pulse laser light to an LN crystal (15). Projection units (13) of the optical fibers (F1 to F5) are made parallel to irradiate the ultra-short pulse laser light (L) projected from the projection units (13), respectively, on terahertz transmission line (A) in the LN crystal (15) with sequential delays. The optical lengths of the transmission paths of the optical fibers (F1 to F5) are set longer as the transmission paths go closer to one side of the parallel direction of the projection units (13).

摘要： A method for measuring a spectrum of a terahertz pulse includes generating a terahertz pulse using an ultrashort pulsed pumping light, generating a white light pulse using an ultrashort pulsed probe light, stretching and chirping the white light pulse modulating the chirped white light pulse such that the terahertz pulse and the chirped white light pulse irradiate into an electro-optic crystal synchronously, so that the chirped white light pulse is modulated by an electric field signal induced at the electro-optic crystal irradiated by the terahertz pulse, detecting a spectrum of chirped white light pulse modulated at the electro-optic modulating step by a multi-channeled detector, analyzing an electric field of the teraherz pulse irradiated to the electro-optic crystal from the spectrum of the chirped white light pulse detected by the multi-channeled spectrum detecting step, and transforming the analyzed electric field signal into a frequency spectrum of the terahertz pulse.
