This dataset were calculated by photocurrent model in Matlab.In the first, few-cycle laser pulse focused in air to generate air-plasma, then photocurrent model was used to calculated the local terahertz emission in whole Rayleigh length. Then the diffraction was considered in far field terahertz radiation calculated, becaue of the reversed local terahertz waveform polarity, off-axis phase matching process make the far field distribution shown a ring-shaped pattern which is driving pluse carrier-envelope phase-dependent.In local coordinate, dt = 0.08 fs, dx = dy = 5 μm, dz = 1000 μm, total volume is 100 μm * 100 μm * 30000 μm.In far field, dx = dy = 1000 μm, detection screen is 225000 μm * 225000 μm.
