Abstract
In a terahertz wave generation apparatus including a first non-linear optical crystalon which first laser Land second laser Lfrom laser generation meansare incident to generate terahertz wave TH, the laser generation means includes a second non-linear optical crystalon which laser having the same wavelength as that of the second laser is incident to generate idler light Lincluding a plurality of wavelengths, and makes the idler light Lgenerated from the second non-linear optical crystal incident on the first non-linear optical crystal as the first laser L, to generate terahertz wave including a plurality of wavelengths from the first non-linear optical crystal, and wavelength selection means including a transmission section which transmits an idler light having the specific wavelength in the idler light including the plurality of wavelengths can be provided, as needed. Thus, terahertz wave having a high output power and including a plurality of wavelengths can be obtained, and the wavelength selection means easily obtains a required terahertz wave having the specific wavelength.
