Fig.#cod#x00A0;5. Energy dependence of the cascaded wavelength conversion process on the wavelength. Temperature varies from 30#cod#x00A0;#cod#x00B0;C to 200#cod#x00A0;#cod#x00B0;C. Open circles and squares representing the OPG signal and SFG were measured by an energy meter equipped with a Si optical sensor. Open triangles beyond 3#cod#x00A0;#cod#x03BC;m are OPG idler energy calculated from the Manley#cod#x2013;Rowe relation.
