Scientists develop invisible anti-counterfeit labels

Researchers from ITMO University and St. Petersburg Academic University developed a new technology for marking authentic goods. Manufacturers will be able to label electronics, drugs, jewelry, and other products with invisible ...

Researchers use infrared light to detect molecules

Ordinary solid-state lasers, as used in laser pointers, generate light in the visible range. For many applications, however, such as the detection of molecules, radiation in the mid-infrared range is needed. Such infrared ...

Researchers develop a high-power, portable terahertz laser

Researchers at MIT and the University of Waterloo have developed a high-power, portable version of a device called a quantum cascade laser, which can generate terahertz radiation outside of a laboratory setting. The laser ...

Music goes terahertz

An international research team from Germany, Italy, and the U.K. has developed a key photonics component for the terahertz spectral range. By mixing electronic resonances in semiconductor nanostructures with the photon field ...

Old X-rays, new vision: A nano-focused X-ray laser

Imagine taking movies of the fastest chemical processes, or imaging atomic-scale detail of single virus particles without damaging them. Researchers from Japan have advanced the state-of-the-art in such endeavors, by enhancing ...

Terahertz technology escapes the cold

Terahertz (THz) radiation is a bit like a treasure chest that resists being opened fully. Residing in the electromagnetic spectrum between the infrared and microwave regions, THz radiation combines a range of properties that ...
