Research into terahertz technology is now receiving increasing attention around the world,
and devices exploiting this waveband are set to become increasingly important in a very …

Organic π‐conjugated crystals with second‐order optical nonlinearity are considerably
attractive materials for diverse terahertz (THz) wave photonics. An overview of the research …

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 …

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 review the generation of broadband THz radiation from femtosecond photo‐induced gas
plasmas, with an emphasis on the highly efficient “AC‐bias” case where the plasma is …

Terahertz radiation with a Bessel beam profile is demonstrated experimentally from a two-
color laser filament in air, which is induced by tailored femtosecond laser pulses with an …

We observe off-axis phase-matched terahertz generation in long air-plasma filaments
produced by femtosecond two-color laser focusing. Here, phase matching naturally occurs …

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 …

Interest of the research in terahertz (THz) wave has been strongly motivated by its wide
applications in the fields of physics, chemistry, biology, and engineering. Developing …

Strong terahertz (THz) electric and magnetic transients open up new horizons in science
and applications. We review the most promising way of achieving sub-cycle THz pulses with …
