Three-wavelength generation from cascaded wavelength conversion in monolithic periodically poled lithium niobate |
Fig.#cod#x00A0;4. Dependence of the wavelengths of SFG, and of the OPG signal and idler, on the phase matching temperature. Experimental data of the OPG signal and SFG output, which agree quite well with the published Sellmeier equation, were measured by a spectrometer, and the OPG idler wavelength was calculated based on energy conservation. |
