| description | The invention discloses a difference frequency terahertz radiation source with high conversion efficiency. The difference frequency terahertz radiation source comprises a pump laser, an isolator, a dual-wavelength energy regulator, a long wavelength generator, a short wavelength generator, a terahertz wave generator and a terahertz wave detector. Wherein the pump laser is used as a pump source, and the pump long wavelength generator and the pump short wavelength generator respectively generate a long wavelength and a short wavelength; the isolator is used for protecting the pump laser; the dual-wavelength energy regulator is used for regulating the energy ratio of the long wavelength and the short wavelength output by the long wavelength generator and the short wavelength generator; the terahertz wave generator generates terahertz waves based on a dual-wavelength (long wavelength and short wavelength) difference frequency effect in the nonlinear crystal; and the terahertz wave detector is used for collecting |
