Abstract. A two-stage infrared up-convertor made of AgGaSe2 and β-BBO crystals has been built up, that can up-convert the mid-infrared radiation of 11–16 μm into the 0.8-μm range where the sensitive photomultiplier can be used. This up-convertor is pumped with a near-infrared radiation of 1.7–1.8 μm wavelength range generated by a β-BBO optical parametric oscillator. In this experiment, we also measured the o-ray refractive index of AgGaSe2 in the 11–16 μm mid-infrared range and extended the fitting range of the Sellmeier equation to the 16-μm wavelength range.
