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

Time-resolved, pulsed terahertz spectroscopy has developed into a powerful tool to study
charge carrier dynamics in semiconductors and semiconductor structures over the past …

Terahertz electromagnetic radiation is extremely useful for numerous applications, including
imaging and spectroscopy. It is thus highly desirable to have an efficient table-top emitter …

Terahertz and millimeter waves penetrate various dielectric materials, including plastics,
ceramics, crystals, and concrete, allowing terahertz transmission and reflection images to be …

Terahertz waves, which lie in the frequency range of 0.1-10 THz, have long been
investigated in a few limited fields, such as astronomy, because of a lack of devices for their …

Recently, the technology of terahertz (THz) waves, which have been called undeveloped
electromagnetic waves, has been making remarkable progress. In addition to the …

We generated an ultrabroadband infrared pulse ranging from far infrared to 200 THz through
a plasma by focusing a hollow-fiber compressed intense 10-fs pulse and its second …

Recent progress of the coherent light synthesis technology has brought the generation of
single-cycle pulses within our reach. To exploit the full potential of such a single-cycle pulse …

We generated ultrabroadband coherent infrared pulses in a spectral range of 1–200 THz
through the use of air plasma produced by hollow fiber compressed submillijoule 10-fs …

For terahertz (THz) wave generators based on organic electrooptic crystals, their intrinsic
phonon modes are playing an essential role in THz generation characteristics. Here, this …
