Terahertz radiation (THz), electromagnetic radiation with frequencies ranging from 0.1 and 10 THz, is central to the ...

Scientists have known about terahertz waves for years. Their unique properties suggest that these waves could enable ...

This involves shining a laser or other high-power light source onto a photoconductive material, which creates a fast electrical pulse. When this pulse passes through a resonant cavity, it generates ...

Using a terahertz laser, scientists successfully vibrated atoms at the same frequency as the material’s collective frequency, or phonons, nudging the material out of its antiferromagnetic state.

Thin-disk single-cavity dual-comb lasers (TDSCs) offer a promising alternative to traditional dual-comb systems, simplifying ...

Researchers have now demonstrated this effect using single-cycle terahertz pulses — instead of optical pulses — in a variety of liquids. In a laser system, the Kerr effect can be used to ...

Using a novel surface-sensitive spectroscopy method, scientists explored atomic vibrations in crystalline material surfaces ...

With new laser sources and detectors coming onto the market, terahertz imaging is starting to become a valuable tool for non-destructive testing, process control and quality inspection ...

Researchers have developed a novel metasurface-based method to generate terahertz complex vector light fields using surface ...
