The cross-sections for free-free processes in electron-argon scattering in the presence of a pulsed CO2 laser have been measured as a function of laser flux. This represents the first attempt at an experimental investigation of the theoretical predictions contained in the Kroll-Watson equation. The dependence of the cross-sections on the various experimental parameters is discussed and we stress the advantages of using moderate laser powers (107W/cm 2) to carry out these tests of the fundamental interactions between free electrons and photons in the presence of an atomic potential.
