Over the past decade, breakthroughs in the generation and control of ultrafast high-field
terahertz (THz) radiation have led to new spectroscopic methodologies for the study of light …

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 …

In this paper, we will review both past and recent progresses in the generation, detection
and application of intense terahertz (THz) radiation. We will restrict the review to laser based …

We investigate high-power terahertz (THz) generation in two-color laser filamentation using
terawatt (TW) lasers including a 0.5 TW, 1 kHz system, as well as 2 and 30 TW systems both …

We generated an ultrabroadband infrared pulse ranging from far infrared to 200 THz through
a plasma by focusing a hollow-fiber compressed intense 10-fs pulse and its second …

Two-dimensional (2-D) transverse photocurrent generation is studied and applied to control
and optimize terahertz energy and polarization in two-color, laser-produced air filaments. A …

Abstract The concept of Terahertz Field-Induced Second Harmonic (TFISH) Generation is
revisited to introduce a single-shot detection scheme based on third order nonlinearities …

We report the observation of terahertz field-induced second harmonic (TFISH) generation
produced by directly mixing an optical probe beam onto femtosecond plasma filaments. The …

We generated ultrabroadband coherent infrared pulses in a spectral range of 1–200 THz
through the use of air plasma produced by hollow fiber compressed submillijoule 10-fs …

Raman scattering has found renewed interest owing to the development of gas-filled hollow-
core fibers, which constitute a unique platform for exploration of novel ultrafast nonlinear …
