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

This innovative approach has been experimentally verified, indicating its potential for improving the efficiency of THz laser sources[2]. Phase-matching conditions are also critical in the ...

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.

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

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 ...
