"data manipulation velocity and energy efficiency... hybrid laser pulse combining 2 polarizations allows control ultrafast laser-light-induced currents... As laser vector potential couples directly to crystal quasi-momentum, a linearly polarized single cycle pulse with duration comparable to that of the circularly polarized pulse: such a pulse will evidently be in the "THz window" of 1 THz to 50 THz...polarization determining direction and amplitude of light induced current"
