Terahertz time-domain spectroscopy (THz-TDS) is a powerful technique for material's
characterization and process control. It has been used for contact-free conductivity …

Organic π‐conjugated crystals with second‐order optical nonlinearity are considerably
attractive materials for diverse terahertz (THz) wave photonics. An overview of the research …

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 …

Low-frequency currents induced by ultrashort laser-driven ionization can emit extremely
broadband, single-cycle terahertz pulses. We present a model that predicts a strong …

Ultrashort terahertz pulses derived from femtosecond table-top sources have become a
valuable tool for time-resolved spectroscopy during the last two decades. Until recently, the …

Terahertz (THz) waves show great potential in nondestructive testing, biodetection and
cancer imaging. Despite recent progress in THz wave near-field probes/apertures enabling …

The overall goal of photonics research is to understand and control light in new and richer
ways to facilitate new and richer applications. Many major developments to this end have …

We observe off-axis phase-matched terahertz generation in long air-plasma filaments
produced by femtosecond two-color laser focusing. Here, phase matching naturally occurs …

Interest of the research in terahertz (THz) wave has been strongly motivated by its wide
applications in the fields of physics, chemistry, biology, and engineering. Develo** …

In the widely studied two-color laser scheme for terahertz (THz) radiation from a gas, the
frequency ratio of the two lasers is usually fixed at ω 2/ω 1= 1: 2. We investigate THz …
