We develop a one-dimensional model of THz emissions induced by laser-driven, time-
asymmetric ionization and current oscillations in a hydrogen gas. Our model highlights …

Two-color laser field-induced plasma filaments are efficient broadband terahertz (THz)
sources with intense THz waves emitted mainly in the forward direction, and they have been …

An array of filaments in air is numerically shown to be an efficient tool to direct the energy of

Two-color photoionization produces a cycle-averaged current driving broadband, conically
emitted THz radiation. We investigate, through simulation, the processes determining the …

We measured the key characteristics of the backward terahertz (THz) emission from a two-
color femtosecond laser spark in air: waveform, spectrum, and energy. Through the …
