In research published in APL Photonics, the team described using diamond crystals and the Raman effect—where laser light stimulates vibrations in materials and then scatters off those vibrations—to ...

A research team has successfully developed a self-locked Raman-electro-optic (REO) microcomb on a single lithium niobate chip. By synergistically harnessing the electro-optic (EO), Kerr, and Raman ...

Indian physicist K.S. Krishnan spent months in a darkroom testing 65 liquids to prove what the world now calls the Raman ...

Raman spectroscopy is a highly efficient technique used to identify chemicals. While the Raman Effect has been known for almost 100 years, recent developments have enabled Raman spectrometers to be ...

Raman spectroscopy has been highlighted as a vital tool for characterizing 2D materials-based van der Waal heterostructures. In this article, we explore its applications in analyzing graphene, TMDs ...

Engineers at Johns Hopkins University say they are using a non-invasive optical probe to understand the complex changes in tumors after immunotherapy. Their method combines detailed mapping of the ...

Laser wavelength selection, a critical determinant of accuracy and data quality, is guided by factors such as resonance, fluorescence, and sample absorption. Ensuring the correct laser wavelength ...

Raman spectroscopy, compatible with molecular and material samples, is one of the most popular quantitative and qualitative spectroscopic techniques. A sample has a distinct Raman “fingerprint” that ...
