Abstract
Two monochromatic electromagnetic waves of identical frequencies propagate in a spatially uniform plasma. The two waves enforce the development of an asymmetrical electron distribution function and an increase in the kinetic energy of the electrons. By considering a Fokker-Planck collision term the energy transferred to the ions from the plasma electrons is calculated. As a function of time, the energy expression contains a linear secular term and a sinusoidal term. It is also found that light absorption through collisions is more efficient than expected for a plasma in which only inverse bremsstrahlung takes place.
