Embodiment Construction
[0034] The present invention is based on a THz wave generating system of two parameter down-conversion processes and a THz wavelength detection system of a parameter down-conversion process, such as figure 1 As shown, the pump source 28 of the THz wave generating system simultaneously pumps the THz wave parametric oscillator 29, the THz wave parameter generator 30 and the THz wavelength detection system 31, and the signal light generated by the THz wave parametric oscillator 29 is the THz wave parametric The generator 30 provides the signal light for the difference frequency, and the THz wave parametric oscillator 29 and the THz wave parametric generator 30 simultaneously output the THz wave (idler frequency light) whose wavelength changes synchronously, so as to achieve the purpose of outputting double terahertz waves with a single pump source; At the same time, the THz wavelength at this time is obtained by the THz wavelength detection system 31 and the THz wave parametric os...
