Abstract
The results of experimental studies of conditions for THz emission generation in laser filament created by focused ultrashort laser pulse of Ti: Sapphire complex are presented. The influence of magnitude and direction of applied external electric field, energy and polarization of pump radiation in one- and two-color optical schemes on the intensity, divergence, and polarization of THz radiation are investigated. THz spectra is estimated and optimal generation conditions are discussed.
