Abstract

As distinct from numerous papers where the problem of the electron thermal conductivity limitation is considered to be a consequence of arising plasma turbulence this paper deals with a "classic mechanism" of limitations. It has been shown that the above-mentioned limitation follows from the condition of the plasma quasi neutrality conservation on the absorption area near the surface of a target irradiated by a laser pulse, where the electron density is critical for the given laser wave length. The thermal conductivity limitation which is discussed below complies with experimental data.
