Abstract
A four-wave interaction of CO2 laser radiation was studied. The pump wave power was 3?5 W and the signal wave power was 0.5?0.8 W. The nonlinear medium was gaseous SF6. The pressure dependence of the reflection coefficient was determined (a maximum was of the order of 0.1 %). The influence of heating of SF6 by CO2 laser radiation was considered.
