| (a) Time-varying electronic currents produced by plasma in case (i) (without 3 ω pulse, blue line), case (ii) ( θ 3 = 0, green line), and case (iii) ( θ 3 = π , red line). (b) Zoomed portions of curves in panel (a). (c) Time-varying spectra of the three cases. (d) Time-varying THz waveforms of the three cases. |
