Abstract :
Refractive indexes of AgGaS/sub 2/ are measured using a tunable CO/sub 2/ laser at 9-11 mu m, Nd:YAG, and He-Ne laser lines and compared with previous values. The phasematching angles calculated for difference-frequency mixing, upconversion, and parametric oscillation are found to agree better with the experimental values.<>
