Unusual optical properties of dense non-equilibrium plasmas
Third harmonic generation in the skin layer of a hot dense plasma
The third harmonic generation of a pump wave, resulting from the electron-ion collision frequency dependence on the electric field in the skin-layer of a hot dense plasma is investigated. The relation of the current third harmonic with the high-frequency field in the skin-layer is established for arbitrary ratios of the electron-ion collision frequency to the field frequency. For arbitrary ratios of these two frequencies the field structure inside the skin-layer is determined, and the field of the wave irradiated by the plasma at tripled frequency too is calculated. It has permitted to find the explicit dependencies of the third harmonic generation efficiency on the plasma and pump field
