Abstract

Conditions for THz generation in the plasma of a filament produced by ultrashort laser pulses in air under aberrations in a one- and two-color optical scheme are observed. Possibilities are discussed of controlling the THz radiation pattern by application of an electric field and introduction of aberrations in the laser beam.

Keywords:
