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 ...
Engineers and applied physicists have laid the foundations for a new type of “plug and play” laser — the Raman injection laser — and in the process, several key innovations in laser technology. The ...
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 ...
With Raman microscopy, there's an additional layer of complexity: fluorescence. Particle fluorescence can overwhelm the Raman signal and make routine analysis more challenging. In comparison, IR ...
Make accurate measurements within seconds Use SpecSuite software to create procedures and optimize processes Measure samples with a variety of accessories in nearly any container The NxG family ...
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, ...
BRAVO is a portable Raman spectrometer designed for rapid identification and authentication of raw materials. It delivers ...

Scientists find hemoglobin traces in dinosaur bones once thought impossible to preserve for millions of years
Scientists report chemical evidence that fragments of hemoglobin, the molecule responsible for carrying oxygen in blood, may still exist inside certain dinosaur fossils. Using a specialized ...
Laser sources operating at the 1.2 μm wavelength band have some unique applications in photodynamic therapy, biomedical diagnosis and oxygen sensing. Additionally, they can be adopted as pump sources ...
