Suppressing stimulated Raman side-scattering with vector light

Matter and Radiation at Extremes, 2023
Recent observations of stimulated Raman side-scattering (SRSS) in different laser inertial confinement fusion ignition schemes have revealed that there is an underlying risk of SRSS on ignition. In this paper, we propose a method that uses the nonuniform

Phase aspects of (broadband) stimulated Raman scattering

Reviews in Analytical Chemistry, 2012
The phase of the molecular response can be exploited to improve selectivity without sacrificing speed in both narrowband and broadband coherent anti-Stokes Raman scattering (CARS) microscopy, both of which will be considered in this review of the work ...

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,

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

Simulation of stimulated Brillouin scattering and stimulated Raman scattering in shock ignition [PDF]

Physics of Plasmas, 2016
We study stimulated Brillouin scattering (SBS) and stimulated Raman scattering (SRS) in shock ignition by comparing fluid and particle-in-cell (PIC) simulations. Under typical parameters for the OMEGA experiments [Theobald et al., Phys. Plasmas 19, 102706 (2012)], a series of 1D fluid simulations with laser intensities ranging between 2 × 1015 and 2 ...
