Raman and Brillouin scattering are inelastic scattering processes in which the wavelength of the scattered radiation is different from that of the incident light and a change in the internal energy of ...

Schematic representation of Raman spectroscopy. After the sample (molecule) is exposed to an intense beam of monochromatic light in the frequency range of visible, near-infrared or near-ultraviolet ...

Most people had attempted to create a laser based on stimulated emission, but we used stimulated Raman scattering instead. Demonstrating the first continuous-wave Raman laser in silicon was a ...

The schematic diagram [Figure (b)] shows that the Stokes beam is modulated with an electro-optic modulator (EOM, M350-160 KD*P, Conoptics) at a couple of MHz by using a square-wave function-generator ...

"We aim to apply our spectrometer to microscopy, enabling the capture of 2D or 3D images with Raman scattering spectra.

By vertical, oil & gas is projected to hold largest market share in distributed fiber optic sensor market by 2030.

Frequency shifts are thus measured based on the amounts of energy involved in the transition between the initial and final stages of the scattering molecule. The Raman effect clarifies the ...
