摘要：

Difference frequency generation under mixing of repetitively-pulsed CO- and CO2-laser radiation inAgGaSe(2), BaGa2GeSe6 and PbIn6Te10 nonlinear crystals was studied. Efficiency and refractive indices were examined for this frequency conversion into the long-wave domain of similar to 12-20 mu m in the mid-IR. The highest frequency conversion efficiency of 10(-4) was obtained for a relatively new PbIn6Te10 crystal, which is an order of magnitude higher than previous results.
