Employing a THz polarization-resolved air-biased-coherent-detection (ABCD) scheme, the polarization of terahertz wave generated in gases ionized by circularly-polarized femtosecond pulse and its linearly-polarized second-order harmonic has been analyzed.It shows the THz polarization state, including the direction and ellipticity, can be controlled by the relative phase and Rayleigh range of the pulses respectively.Comparing the results with that in the case of linearly dual-color pulse used, we reveal the mechanism in the elliptically polarized THz generation.
