Abstract

We study the angular and frequency-angular distributions of the low-frequency part (0.3-3 THz) of the terahertz emission from two-color femtosecond plasma spark experimentally and in 3D + time numerical simulations. Our experiments and simulations show, that the weakening in the focusing conditions results in the squeezing of the THz angular distribution and the formation of the bright conical emission.
