Optical Kerr Gating as a Strategy for Noise Reduction in Femtosecond Stimulated Raman Spectroscopy

Journal of Raman Spectroscopy, EarlyView.
We report an experimental approach, where an Optical Kerr gate is incorporated with Femtosecond Stimulated Raman Spectrometry (FSRS). The gate functions as a temporal filter that preferentially suppresses the FSRS inherent background. FSRS spectra are reported with the Kerr‐gated methodology with significantly improved SNR compared to the conventional ...

Exploring, tailoring, and traversing the solution landscape of a phase-shaped CARS process [PDF]

, 2010
Pulse shaping techniques are used to improve the selectivity of broadband CARS experiments, and to reject the overwhelming background. Knowledge about the fitness landscape and the capability of tailoring it is crucial for both fundamental insight and ...

SMILE: Extraction‐free submicron‐resolution mapping of lipid chain length and unsaturation by stimulated Raman imaging

VIEW, EarlyView.
In this work, we develop submicron‐resolution mapping of intracellular lipid elements (SMILE) as an extraction‐free vibrational spectroscopic imaging platform based on hyperspectral stimulated Raman scattering microscopy with a spectral analysis pipeline for pixel‐resolved lipid profiling.

Advances in Femtosecond Coherent Anti-Stokes Raman Scattering for Thermometry

Photonics
The combustion process is complex and harsh, and the supersonic combustion flow field is also characterized by short duration and supersonic speed, which makes the real-time diagnostic technology for the transient environment extremely demanding.

Cell‐MICS: Detecting Immune Cells With Label‐Free Two‐Photon Autofluorescence and Deep Learning

Journal of Biophotonics, Volume 19, Issue 4, April 2026.
We demonstrate multiphoton imaging with computational specificity for label‐free cell identification (cell‐MICS). Based on the intrinsic contrast of two‐photon induced autofluorescence from metabolic proteins, a deep neural network is able to distinguish various different immune cell types. The system's performance is stable and efficient.
