A hammer impact must be repeated for each scan point to measure points consecutively with a Polytec Scanning Laser Vibrometer. As a result, automated modal hammers such as the SAM, developed by ...
New excitation method of stimulated Raman scattering achieves natural-linewidth-limit spectral lines
SRL has a linear relation to the molecular concentration and the Raman cross section, and it can be detected by classical heterodyne detection method to achieve the same shot-noise-limited sensitivity ...
A new two-step excitation technique efficiently generates and separates different modes of hyperbolic polaritons - directional nanoscale light-matter modes with extreme electromagnetic field ...
New excitation method of stimulated Raman scattering achieves natural-linewidth-limit spectral lines
Stimulated Raman Scattering (SRS) has been developed as an essential quantitative contrast for chemical imaging in recent years. However, the spectral resolution of the mainstream SRS modalities is ...
Illustration of nanolight pseudo-birefringence. Two-step excitation via a light-illuminated antenna and a sharp boundary efficiently excites higher-order light-matter waves (hyperbolic phonon ...
