Stimulated Raman spectroscopy has become a powerful tool to study the spatiodynamics of molecular bonds with high sensitivity resolution and speed However the sensitivity and speed of state-of-the-art stimulated Raman scattering spectroscopy are currently limited by the shot-noise of the light beam probing the Raman process Here we demonstrate in a proof-of-principle experiment an

Rapid histology of brain tissues with sufficient diagnostic information has the great potential to aid neurosurgeons during operations Stimulated Raman Scattering (SRS) microscopy is an emerging label-free imaging technique with the intrinsic chemical resolutions
Here we present the first applications of stimulated Raman scattering (SRS) microscopy a nonlinear optical Raman technique to samples of mineralogical interest Combined with second harmonic generation microscopy SRS offers a multimodal tool for rapid imaging of mineral samples with chemical specificity structural sensitivity and excellent three‐dimensional resolution

Stimulated Raman scattering (SRS) microscopy that is capable of both high-speed imaging and rapid spectroscopy will be advantageous for detailed chemical analysis of heterogeneous biological specimens We have developed a system based on spectral focusing SRS technology with the integration of a rapid scanning optical delay line which allows continuous tuning of SRS spectra by scanning a
Here a phenotypic platform that rapidly produces AST results by femtosecond stimulated Raman scattering imaging of deuterium oxide (D 2 O) metabolism is reported Metabolic incorporation of D 2 O into biomass in a single bacterium and the metabolic response to antibiotics are probed in as short as 10 min after culture in 70% D 2 O medium the fastest among current technologies

Stimulated Raman scattering (SRS) microscopy In SRS the intensity of the energy transfer from the pump wavelength to the Stokes laser wavelength is measured as a signal There are two ways to measure SRS signals one is to measure the increase of power in Stokes laser which is called stimulated Raman gain (SRG)
The scheme combines the concept from stimulated depletion microscopy with femtosecond stimulated Raman scattering The suppression of the Raman signal in a three-beam setup with only two involved wavelength-components was accomplished by the saturation of the Raman scattering
