Extreme nonlinear interactions of THz electromagnetic fields with matter are the next frontier
in nonlinear optics. However, reaching this frontier in free space is limited by the existing …

Terahertz (THz) radiation produced by the filamentation of two-color pulses over long
distances in argon is numerically investigated using a comprehensive model in full space …

Methods recently proposed for generating unipolar pulses in nonlinear media in terahertz
and optical electromagnetic ranges are reviewed. Such pulses have nonzero “electric …

Through the ionization process, the very air that we breath is capable of generating terahertz
(THz) electromagnetic field strengths greater than 1 MV/cm, useful bandwidths of over 100 …

Nonlinear THz photonics is probably the last frontier of nonlinear optics. The strength of both
the electric and the magnetic fields of these ultrashort low-frequency light bunches opens …

Two-color plasma, induced by two lasers of different colors, can radiate ultra-broadband and
intense terahertz (THz) pulses, which is desirable in many technological and scientific …

We demonstrated terahertz (THz) radiation generated from a three-color laser-excited
filament in air for a wide tuning range and various wavelength ratios of the pump laser …

Terahertz pulses are very popular because of their numerous applications, for example in
security. Located between microwaves and optical waves in the electromagnetic spectrum …
