Terahertz radiation has become an important diagnostic tool in the development of new
technologies. However, the diffraction limit prevents terahertz radiation (λ≈ 0.01–3 mm) …

The present status and development of strong-field nano-optics, an emerging field of
nonlinear optics, is discussed. A nonperturbative regime of light-matter interactions is …

The cost, size and availability of electron accelerators are dominated by the achievable
accelerating gradient. Conventional high-brightness radio-frequency accelerating structures …

Watching a single molecule move on its intrinsic timescale has been one of the central goals
of modern nanoscience, and calls for measurements that combine ultrafast temporal …

Coherent manipulation of quantum systems with light is expected to be a cornerstone of
future information and communication technology, including quantum computation and …

The field of terahertz science and technology has been an active and thriving research area
for several decades. However, the field has recently experienced an inflection point, as …

We present the development of the first ultrafast transmission electron microscope (UTEM)
driven by localized photoemission from a field emitter cathode. We describe the …

Terahertz (THz) imaging can see through otherwise opaque materials. However, because of
the long wavelengths of THz radiation (λ= 400 μm at 0.75 THz), far-field THz imaging …

Lightwave-driven terahertz scanning tunnelling microscopy (THz-STM) is capable of
exploring ultrafast dynamics across a wide range of materials with ångström resolution (10 …

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 …
