Recent years have witnessed a rapid development of sources for intense terahertz (THz)
pulses and an increasing number of their applications. The advent of laser pulses with …

Coherent transition radiation in the terahertz (THz) region with energies of sub-mJ/pulse has
been demonstrated by relativistic laser-driven electron beams crossing the solid-vacuum …

The Maxwell equations-based 3D-analytical solution for the terahertz (THz) half-cycle
electromagnetic wave transition radiation pulse has been found. This solution describes …

We present a novel scheme to obtain robust, narrowband, and tunable THz emission using
a nano-dimensional overdense plasma target, irradiated by two counter-propagating …

Terahertz (THz) emissions from fast electron and ion currents driven in relativistic,
femtosecond laser-foil interactions are examined theoretically. We first consider the radiation …

Terahertz (THz) radiation has broad applications ranging from medical imaging to
spectroscopy. One viable source of high‐intensity THz radiation is the Smith–Purcell (SP) …

Ball lightning, a fireball sometimes observed during lightnings, has remained unexplained.
Here we present a comprehensive theory for the phenomenon: At the tip of a lightning stroke …

The development of tabletop intense terahertz (THz) radiation sources is extremely
important for THz science and applications. This paper presents our measurements of …

We demonstrate an intense broadband terahertz (THz) source based on the interaction of
relativistic-intensity femtosecond lasers with aligned copper nanorod array targets. For …

We present a particle-in-cell (PIC) analysis of terahertz (THz) radiation by ultrafast plasma
currents driven by relativistic-intensity laser pulses. We show that, while the I 0 λ 0 2 product …
