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 ...

The review discusses innovations in quartz-enhanced laser spectroscopy, emphasizing QEPAS and LITES for improved sensitivity in trace gas sensing technologies.

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 ...

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 ...
