Experiments on THz pulse generation from single and multiple filaments in air using single or two-color technique will be discussed. Its application to sensing molecular rotational wave packet revival will be given. Stand-off detection of THz from a distance through monitoring nitrogen fluorescence in a filament was observed. The physics seems to be due to population trapping in the wake of strong field interaction with nitrogen molecules inside the filament. Article not available.
