Harmonic generation in the extended plasmas produced on the non-metal targets

详细

The review of the high-order harmonic generation (HHG) studies in the extended plasma plumes produced on the surfaces of non-metal targets (elemental semiconductors, oxygen- and fluorine-contained crystals) is presented. The objective of those studies was to reveal the attractive properties of non-metal plasmas. We discuss the results of HHG optimization in the above plasma plumes using different methods. These studies demonstrate the usefulness of the plasma harmonic approach for the analysis of the nonlinear optical and spectroscopic properties of the extended laser-produced plasmas formed on the non-metal surfaces.
