Abstract

Frequency-angular distributions for THz emission in the range of 0.1–3 THz generated in a single-color laser filament plasma both under an electrostatic field and without one are experimentally studied for what we believe is the first time. The angular distribution for various spectral components of this THz emission is demonstrated to differ significantly. The maximal propagation angles for these components increase under the electric field. The angular distribution for the low-frequency THz emission depends significantly on the laser pulse energy in contrast to the case of no electric field. An increase in the laser pulse energy leads to a decrease of the propagation angles for low-frequency THz emission and to disappearance of the local minimum in the angular distribution on the propagation axis.
