Abstract

The phenomenon of ultrashort laser-pulse filamentation in transparent gases and liquids is represented by the localization of laser energy in a thin string of light called filament. This string is created under the joint action of radiation self-focusing and defocusing in the plasma, which is produced by the same propagating laser pulse that limits the self-focusing collapse. Ultrashort filamenting pulse emits continuum spanning from ultraviolet to terahertz range. The origin of low-frequency terahertz (THz) radiation (0-15 THz) originates from the ionization-induced photocurrent, while the higher-frequency THz radiation comes from the Kerr nonlinearity of neutral molecules.
