Abstract
In a THz wave generator for generating a THz wave from a THz wave generating element by inputting a plurality of laser beams having different wavelengths to the THz wave generating element, all of the plurality of laser beams are formed into a pulse beam by the pulse generator and the pulse beam is amplified by a single optical amplifier E to which the laser beams are inputted with polarization planes of the laser beams being controlled, and then the pulse beam is inputted to the THz wave generating element F. Preferably, the plurality of laser beams having different wavelengths are generated by inputting single wavelength beam to a multi wavelength generator from single mode laser light source and by inputting light waves having a plurality of wavelengths generated from the multi wavelength generator to wavelength selecting means.
