Gisela Eckhardt was one of the early pioneers in laser physics, discovering the principle behind the Raman laser in 1962. Valdas Pasiskevicius, Richard Mildren and David Burman tell the largely ...

Raman laser technology exploits the nonlinear process of stimulated Raman scattering (SRS) to convert the frequency of a primary laser beam into new wavelengths. By utilising Raman-active crystals or ...

The first electrically-pumped Raman laser is reported in a paper in Nature. A team of US scientists has made the world’s first electrically-driven Raman laser. The development could lead to a new type ...

Raman spectroscopy is a non-destructive analytical method that generates complex information about the phase, chemical structure and crystallinity of sample matter. A range of molecular interactions ...

You wouldn’t think that shaking something in just the right way would be the recipe for creating laser light, but as [Les Wright] explains in his new video, that’s pretty much how his DIY Raman laser ...

Despite its progressive nature, functionality and flexibility, Raman Spectroscopy is a complex, often challenging procedure demanding a combination of high quality tools employed with appropriate, up ...

Diabetes management requires a person to regularly monitor their glucose levels. For decades, this almost always required ...

Intel's optical engineers have notched up another first: a cascaded Raman laser built in silicon that they believe could be used in gas sensing applications. Researchers at Intel have demonstrated for ...

Agere Systems has developed a pump laser using Raman amplification. Aimed at submarine optical networks, Raman amplification boosts signals more efficiently than erbium-doped amplifiers, which are ...

Although wooly mammoths are long gone, their recovered ivory lives on as a legal alternative to banned elephant ivory. Scientists can now use lasers to differentiate between the two materials, ...
