| (a) Time-varying electron current produced by plasma in the case (iv) (without 3 ω pulse, blue line), case (v) ( θ 3 = −0.62 π , green line), and case (vi) ( θ 3 = 0.58 π , red line). (b) Zoomed portions of curves in panel (a). (c) Spectra of the three cases. (d) THz waveforms of the three cases. |
