Multicolor stimulated Raman scattering microscopy [PDF]

Molecular Physics, 2012
Stimulated Raman scattering (SRS) microscopy has opened up a wide range of biochemical imaging applications by probing a particular Raman-active molecule vibrational mode in the specimen.

Fluorescence-free single-molecule microscopy via electronic resonance stimulated Raman scattering [PDF]

Nature Communications
Vibrational spectroscopy is a powerful tool for spectral imaging of biological samples, thanks to its narrow bandwidth (10 cm⁻¹) compared to fluorescence.

Stimulated Brillouin scattering of backward stimulated Raman scattering [PDF]

Scientific Reports, 2020
AbstractThe rescattering of backward stimulated Raman scattering (BSRS) by stimulated Brillouin scattering (SBS) is found in the high electron density region by relativistic Vlasov-Maxwell simulation and particle-in-cell (PIC) simulation, where the BSRS is in the regime of absolute instability and dominates in all the scatterings.

Mid-Infrared Multispectral Gaseous Stimulated Raman Scattering Laser

Applied Sciences, 2021
We demonstrated mid-infrared gaseous stimulated Raman scattering lasers in free space. Mixed gases of hydrogen and deuterium were used as Raman gain media in one Raman cell.

Transient Stimulated Raman Scattering [PDF]

SIAM Journal on Mathematical Analysis, 1992
The authors consider the system of partial differential equations \[ {\partial u\over \partial\xi}= -zv,\;{\partial v\over \partial\xi}= \bar zu,\;{\partial z\over \partial\tau}= u\bar v- \gamma z \] which model the interaction of two laser beams with gases when the frequency difference between the beams corresponds to a resonance of the gas molecules.

Stimulated Raman Scattering of Q-Gaussian Laser Beam in an Unmagnetized Plasma [PDF]

Journal of Applied Sciences and Nanotechnology, 2023
This study describes the relativistic q-Gaussian laser beam's stimulated Raman scattering (SRS) in an unmagnetized plasma. Moreover, the influence of the pump laser's relativistic self-focusing on the SRS process has been investigated.

Stimulated Raman Scattering in Ge Nanowires [PDF]

The Journal of Physical Chemistry C, 2020
Investigating group-IV-based photonic components is a very active area of research with extensive interest in developing complementary metal-oxide-semiconductor (CMOS) compatible light sources. However, due to the indirect band gap of these materials, effective light-emitting diodes and lasers based on pure Ge or Si cannot be realized. In this context,

Stimulated Raman scattering simulation for imaging optimization

Journal of the European Optical Society-Rapid Publications, 2021
Two simulation programs of a stimulated Raman scattering microscopy (SRS) imaging system with lock-in amplifier (LIA) detection were developed. SRS is an imaging technique based on the vibrational Raman cross-section as the contrast mechanism and enables
