Field-free molecular alignment can be induced by the strong ultrashort laser pulses. Here, the improvement of the alignment is completed by the coupled pulses of the ultrashort laser pulse and the strong broadband terahertz pulse. The gaseous CO mole

The interaction and the coupling between the plasma filaments introduce some ultrafast phenomena, which not only reveal deep physical mechanisms, but also provide clues to develop the plasma filament-based applications. In this paper, the terahertz (

By applying the well-known transient current model, theoretically investigating terahertz (THz) emission from gas plasma induced by multi-color femtosecond laser pulses has been developed in this work. Instead of static tunneling ionization model, we

A blueshift in frequency spectrum is observed in the supercontinuum radiation from a plasma grating, which is formed by the laser field interference in the overlap region of two noncollinear femtosecond plasma filaments. These two pump laser pulses s

Terahertz pulses, including a main pulse and a small pulse, radiated from two noncollinear femtosecond laser plasma filaments are analyzed with an iris in the terahertz beam. The experimental results exclude the possibility that the small terahertz p
