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 ...

Radial Anisotropy Beneath the Continental U.S. From Surface Wave Phase Velocities
Geochemistry, Geophysics, GeosystemsWe assemble the highest‐resolution data set of Love wave phase velocities measured across the continental U.S. to date, combining observations from ambient noise and teleseismic earthquakes to span a period range between 10 and 120 s.

Ambient‐Light‐Activated Rewritable Optical Patterning in Transparent Long‐Afterglow Garnet Ceramics
Laser &Photonics Reviews, EarlyView.This work demonstrates sunlight‐activated rewritable optical information storage in transparent long‐afterglow Y3Al2Ga3O12:Ce (YAGG:Ce) garnet ceramics fabricated via solid‐state sintering with tetraethyl orthosilicate (TEOS) as a sintering aid. By integrating ambient‐light operability, reversibility, and high optical clarity in a robust ceramic host ...
