Advanced Science, EarlyView.A multi‐technique pump‐probe setup capable of performing both transient reflectivity and time‐resolved Raman spectroscopy after ultrafast excitation, provides a comprehensive understanding of ultrafast electronic and phononic processes. Distinct decay rates for the temperature, frequency, and linewidth of the phonon mode in germanium are observed ...

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 ...

Non-linear label-free imaging through a multimode graded index optical fibre [PDF]
EPJ Web of Conferences, 2020 In recent years, great advances have been made in developing minimal footprint micro-endoscopes using multimode optical fibres (MMF) [1]. By employing wavefront shaping methods the seemingly random speckle pattern resulting from the guiding of coherent ...

Generation of frequency shifted picosecond pulses with low temporal jitter [PDF]
, 1984 Transient stimulated Raman scattering is used for the generation of a frequency shifted picosecond light pulse; part of this Raman shifted pulse is subsequently coherently scattered at a material excitation of a second Raman cell.

Resonance enhanced coherent anti-Stokes Raman scattering. [PDF]
Proceedings of the National Academy of Sciences, 1976 Resonance enhancement of coherent anti-Stokes Raman scattering due to the proximity of the laser frequencies to an electronic transition has been demonstrated for dilute solutions of diphenyloctatetrane in benzene. The Raman contribution to the third order susceptibility is shown to be complex near an electronic resonance and the resulting features of ...

Deep Learning‐Assisted Coherent Raman Scattering Microscopy
Advanced Intelligent Discovery, EarlyView.The analytical capabilities of coherent Raman scattering microscopy are augmented through deep learning integration. This synergistic paradigm improves fundamental performance via denoising, deconvolution, and hyperspectral unmixing. Concurrently, it enhances downstream image analysis including subcellular localization, virtual staining, and clinical ...
