A research group at TU Wien has developed a terahertz radiation source that is both efficient and creates a broad spectrum, generating different wavelengths from the entire terahertz range. Both aspects are said to have broken previously held records.
The research group believes the new radiation source will allow short radiation pulses to be generated with high radiation intensity.

“Terahertz radiation has very useful properties,” said Claudia Gollner from the Institute of Photonics at TU Wien. “It can easily penetrate many materials, but unlike x-rays, it is harmless because it is not ionizing radiation.”
