Abstract
The invention is related to a parametric light generation method and its application and belongs to the technical field of laser and nonlinear optics. The generation method comprises steps as follows: a nonlinear optical material that meets the sum-frequency phase-matched conditions, namely it shall satisfy the energy conservation condition ωp+ωi=ωs and the momentum conservation condition npωp+niωi=nsωs simultaneously, is provided; laser light with a wavelength of λp is injected into the said nonlinear optical material as pump light; then, the material will output signal light with a wavelength of λS, namely the tunable sum-frequency parametric light. With sum-frequency as the basic principle, the invention can realize frequency up-conversion and obtain visible and UV light sources through simple infrared light sources easily.
