A new scheme to generate single-cycle strong terahertz (THz) pulses by ultrashort intense laser pulses incident onto a tenuous plasma slab is proposed. Our theory model suggests that, if τL >2π/ωp with τL the laser pulse duration and ωp the plasma frequency, the emission frequency is around τL−1.

We experimentally investigate the high order harmonic generation (HHG) from aligned CO2 molecules and demonstrate that the modulation inversion of harmonic yield with respect to molecular alignment can be altered dramatically by the intensity of the driving laser pulse. The laser intensity dependence of the angular distributions for the 19th to 27th harmonics is also directly measured.
