Abstract
A terahertz wave generating device according to the present invention comprises a fixed-wavelength pump optical laser that generates a single wavelength pump beam, a variable-wavelength laser that emits a seed beam and is capable of making the wavelength of the seed beam variable, a delay element that delays pulses of the pump beam and a first non-linear crystal that generates terahertz waves by receiving the seed beam, a first pump beam that is not delayed by the delay element and a second pump beam that is delayed by the delay element.
