A Spectral Resolution study in Femtosecond Stimulated Raman Scattering Microscopy [PDF]
EPJ Web of Conferences, 2021 The simultaneous mapping and the specificity of different chemical species are desirable in several biological and biomedical applications. The stimulated Raman Scattering technique is a proven and well-established label-free method to map the ...

Nanoscale nonreciprocity via photon-spin-polarized stimulated Raman scattering
Nature Communications, 2019 Here, the authors introduce and study theoretically and numerically a scheme for breaking time-reversal symmetry and achieving nonreciprocity on the nanoscale, using spin-selective stimulated Raman scattering. These results could pave the way for compact

Ultralow-threshold microcavity Raman laser on a microelectronic chip [PDF]
, 2004 Using ultrahigh-Q toroid microcavities on a chip, we demonstrate a monolithic microcavity Raman laser. Cavity photon lifetimes in excess of 100 ns combined with mode volumes typically of less than 1000 µm^3 significantly reduce the threshold for ...

Sum-frequency ionic Raman scattering
, 2018 In a recent report sum-frequency excitation of a Raman-active phonon was experimentally demonstrated for the first time. This mechanism is the sibling of impulsive stimulated Raman scattering, in which difference-frequency components of a light field ...

Role of spatiotemporal couplings in stimulated Raman side scattering
Physical Review Research, 2023 A high-intensity laser pulse propagating through underdense plasma is prone to parametric instabilities. We report on experiments investigating the influence of a pulse-front tilt (PFT), one of the most common spatiotemporal couplings in the laser focus,

Ultrabroad-bandwidth multifrequency Raman generation [PDF]
, 1994 We report on the modeling of transient stimulated rotational Raman scattering in H2 gas. We predict a multifrequency output, spanning a bandwidth greater than the pump frequency, that may be generated without any significant delay with respect to the ...

Stimulated Raman scattering microscopy for rapid brain tumor histology [PDF]
Journal of Innovative Optical Health Sciences, 2017 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 ...

Single-pulse stimulated Raman scattering spectroscopy [PDF]
Optics Letters, 2011 We demonstrate the acquisition of stimulated Raman scattering spectra with the use of a single femtosecond pulse. High resolution vibrational spectra are obtained by shifting the phase of a narrow band of frequencies in the broadband input pulse spectrum, using spectral shaping.
