Fig. 2 (a) The relationship between the plasma density of the filament and the time delay of the two-color field (Δt1); (b) The generated THz efficiency as a function of Δt1 in the experiment is shown as the black solid line while the simulated THz relative intensities of the empirical model is represented as blue dashed line. Free electron density with different retardations was measured on the filament axis at z=2.7 mm and shown as red dash-dotted line.
