This paper reports on the updated Sellmeier equations for AgGaS2 that provide an excellent reproduction of the 90° phasematching conditions for up-conversion of a CO2 laser to the green spectral range (0.565–0.566 μm) as well as those for difference-frequency generation using wavelengths below 0.7 μm.
