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 ...

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 ...

Raman lasers utilise the process of stimulated Raman scattering to convert incident laser light into new wavelengths via interactions with vibrational modes in crystalline materials. This technology ...

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 ...

While direct Raman detection without this physical offset yields a spectrum rich in the top layer information, an offset geometry collects the detectable Raman signal stimulated in nearly areas, ...

BRAVO is a portable Raman spectrometer designed for rapid identification and authentication of raw materials. It delivers ...

Deep-UV resonance Raman (DUVRR) spectroscopy with excitation at 266 nanometers, matching the maximum UV absorption of mRNA, enables spectral differentiation of mRNA based on its degree of ...

When studying biological systems, understanding structure and chemistry often calls for different approaches. Scanning electron microscopy (SEM) is particularly useful for revealing ultrastructural ...

This article explains the "Raman Concatenation", a measurement approach that can overcome several trade-offs. In general, fluorescence impacts many Raman measurements, necessitating the adoption of ...

Laser lights are usually employed for the Raman spectroscopic analysis. The photons emitted by the laser light are absorbed by the sample, temporarily entering a non-stationary, exceedingly brief ...

High-power fiber oscillators are critical tools for modern industry: they cut and weld tough materials, make precision components for high-end devices, and even support delicate biomedical procedures.
