Short wavelength light generator using nonlinearity of light wave

摘要

More particularly, the present invention relates to a device for generating at least two long-wavelength signals of a red light series in a visible light, electrically converts the long wavelength signals into visible light, converts them into a nonlinear light wave, Blue high-frequency short-wavelength light is generated. The apparatus of the present invention includes signal generators for simultaneously generating the above-mentioned long wavelength signals; A nonlinear processor for converting long wavelength signals from the signal generators into nonlinear light waves by interfering with each other; And a high-frequency optical filter for filtering the output from the nonlinear processor to obtain the short-wavelength light described above. The short wavelength light generating device of the present invention having such a configuration provides an effect of easily generating short wavelength light as compared with a conventional high frequency short wavelength laser device and at the same time reducing cost.
