A review on the recent development of intense laser‐driven terahertz (THz) sources is
provided here. The technologies discussed include various types of sources based on …

Discoveries in quantum materials, which are characterized by the strongly quantum-
mechanical nature of electrons and atoms, have revealed exotic properties that arise from …

In recent years, the notion of'Quantum Materials' has emerged as a powerful unifying
concept across diverse fields of science and engineering, from condensed-matter and …

In this work, we improve the performance of an optically pumped spintronic terahertz emitter
(STE) by a factor of up to 6 in field amplitude through an optimized photonic and thermal …

The far-infrared region of the electromagnetic spectrum (0.3–10 THz), known as the THz
frequency band, is a spectral window with rich scientific opportunities, but is, at present …

Spintronic terahertz emitters are broadband and efficient sources of terahertz radiation,
which emerged at the intersection of ultrafast spintronics and terahertz photonics. They are …

Organic crystals with second-order optical nonlinearity feature very high and ultra-fast
optical nonlinearities and are therefore attractive for various photonics applications. During …

We review the tremendous advances in ultrafast X-ray science, over the past 15 years,
making the best use of new ultrashort X-ray sources including table-top or large-scale …

The availability of high-energy pulses with durations shorter than the period of their carrier
frequency (sub-cycle) will reveal new regimes of strong-field light–matter interactions …

Rectification describes the conversion of an oscillating field or current into a quasi-static one
and the most basic example of a rectifier is an AC/DC converter in electronics. This principle …
