Based on the vectorial model of the dual pulse co-propagation we found that terahertz yield due to four-wave mixing in the filament maximizes for the same temporal delay between 400nm and 800nm pulses as the 400nm signal after the analyzer crossed to its initially linear polarization direction. This optimum delay goes up with increasing geometrical focusing distance and leads to the maximum terahertz yield if the initial 800nm pump and the second harmonic polarization directions are parallel to each other.
