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 ...

Stimulated Raman scattering (SRS) in liquid water is a nonlinear optical phenomenon wherein incident laser light interacts with vibrational modes of water molecules, leading to coherent amplification ...

Cell mass and chemical composition are important aggregate cellular properties that are especially relevant to physiological processes, such as growth control and tissue homeostasis. Despite their ...

(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 ...

Nonlinear Raman microscopy techniques, such as coherent anti-Stokes Raman scattering and stimulated Raman scattering, are widely used to provide chemical and spatial information. A third nonlinear ...

A research team has successfully developed a self-locked Raman-electro-optic (REO) microcomb on a single lithium niobate chip. By synergistically harnessing the electro-optic (EO), Kerr, and Raman ...

Detecting nanoscale plastic pollutants in the environment is a continuing challenge, and their presence is commonly only estimated rather than measured directly. A project at Vienna's TU Wien has now ...

In kitchens, gyms, and office desks across the globe, bottled water is consumed with the quiet assumption that it offers a ...

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 ...

Gisela Eckhardt was one of the early pioneers in laser physics, discovering the principle behind the Raman laser in 1962. Valdas Pasiskevicius, Richard Mildren and David Burman tell the largely ...
