Stimulated Raman scattering, observed first in 1962, has become a versatile tool in diverse fields like including biological imaging, environmental gas sensing, materials characterization, and ...
As a promising clean energy source, hydrogen (H2) requires reliable safety monitoring. However, lacking a permanent dipole ...
A novel method detects hydrogen at extremely low concentrations by enhancing molecular signals, enabling accurate monitoring, and advancing safety in hydrogen-based energy systems.
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 ...
(a) Schematic diagram of the pump burst and the Stokes burst in the time domain. N: number of pulses in burst. ∆τ: inter-pulse temporal separation. φ: pulse-to-pulse offset phase. Ω R: Raman frequency ...
Researchers have developed and demonstrated a new method for high-throughput single-cell sorting that uses stimulated Raman spectroscopy rather than the traditional approach of fluorescence-activated ...
During light scattering, the majority of scattered light undergoes no change in frequency (or energy), in a process referred to as referred to as elastic or Rayleigh scattering. Raman spectroscopy ...
Flow cytometry is an established technique for counting and characterising cells, including blood, stem and cancer cells in biomedicine. The principle involves illuminating cells while they pass along ...
A project at Macquarie University has demonstrated a way to narrow the linewidth of a laser beam by a factor of over ten thousand. Published in APL Photonics, the technique offers a promising route ...
