Extremely strong-field terahertz (THz) radiation in free space has compelling applications nonequilibrium condensed matter state regulation, all-optical THz electron acceleration and manipulation, biological effects, etc. However, these practical are constrained by the absence of high-intensity, high-efficiency, high-beam-quality, stable solid-state light sources. Here, generation single-cycle 13.9-mJ extreme pulses from cryogenically cooled lithium niobate crystals a 1.2% energy conversion...
Abstract Inverse Compton scattering between ultra-relativistic electrons and an intense laser field has been proposed as a major route to generate compact high-brightness high-energy γ-rays. Attributed the inherent synchronization mechanism, all-optical γ-ray source, using one both accelerate scatter via reflection of plasma mirror, demonstrated in proof-of-principle experiments produce x-ray source near 100 keV. Here, by designing cascaded wakefield accelerator high-quality monoenergetic...

Spin rotation is central for the spin manipulation of lepton beams which, in turn, plays an important role investigation properties spin-polarized and examination spin-dependent interactions. However, realization compact ultrafast beams, between longitudinal transverse polarizations, still faces significant challenges. Here, we put forward a novel method (picosecond timescale) relativistic beam via employing moderate-intensity terahertz (THz) wave dielectric-lined waveguide (DLW). The...

We demonstrate terahertz-driven excitation low-frequency PhPs zinc oxide (ZnO) crystals, with their dynamics resolved via time-resolved second harmonic generation (SHG) spectroscopy. By achieving phase matching nine sequential reflections within a millimeter-scale crystal, we observe sustained SHG oscillations 3–4 THz modulation frequencies, optimal extinction...
The miscellaneous applications of terahertz have called for an urgent demand a super intense source. Here, we demonstrate the capability femtosecond laser-driven wires as efficient ultra-intense source using 700 mJ laser pulses. When focused onto wire target, coherent THz generation took place in miniaturized gyrotron-like undulator where emitted electrons move radial electric field spontaneously created on surface. single-cycle pulse generated from target is measured to be radially...
Terahertz radiation can provide unprecedented vistas in physical studies such as transient matter state control and advanced free-electron manipulation. Here, we present one feasible path towards high-repetition-rate, intense THz sources by combining the wire-based source on a consecutively running, wire-conveying tape design. The proof-of-principle experimental results show an upper 30 mW average power output under 1 kHz laser excitation, which presents first most importantly, portable...
The reaction mechanism from alcohols to carbon dots is investigated experimentally and theoretically. Carbon with rich functional groups can be utilized as electrolyte additives optimize the deposition behaviour of Na metal, showing great potential towards metal batteries.
We propose a scheme to minimize the energy spread of an electron beam (e-beam) in cascaded laser wakefield accelerator one-thousandth-level by inserting stage compress its longitudinal spatial distribution. In this scheme, three-segment plasma stages are designed for injection, e-beam length compression, and acceleration, respectively. The trapped injection is transferred zero-phase region at center one period compression where can be greatly shortened owing velocity bunching. After being...
