Characterization of single-crystal synthetic diamond for multi-watt continuous-wave Raman lasers [PDF]
, 2012 A continuous-wave diamond Raman laser is demonstrated with an output power of 5.1 W at 1217 nm. This Raman laser is intracavity pumped by a side-pumped Nd:YLF rod laser: a 43-fold brightness enhancement between the Nd:YLF and diamond Raman lasers is ...

Study of dynamical heterogeneities in colloidal nanoclay suspensions approaching dynamical arrest
Scientific Reports, 2017 The dynamics of aqueous Laponite clay suspensions slow down with increasing sample waiting time (t w ). This behavior, and the material fragility that results, closely resemble the dynamical slowdown in fragile supercooled liquids with decreasing ...

X-Ray Flares in the Long-term Light Curve of Low-luminosity Active Galactic Nucleus M81*
The Astrophysical Journal, 2023 Most active galactic nuclei at the center of the nearby galaxies have supermassive black holes accreting at sub-Eddington rates through hot accretion flows or radiatively inefficient accretion flows, which efficiently produce jets.

Microplastics, 2023 Microplastics (MPs) are ubiquitous and evasive in nature. They can be found in complex agricultural matrices like soil and compost. In the literature, extracting MPs from soil is more prevalent; nonetheless, the same instruments in extraction in soil ...

Design and evaluation of Raman reporters for the Raman-silent region [PDF]
Nanotheranostics, 2022 Rationale: Surface enhanced Raman scattering (SERS) is proving to be a useful tool for biomedical imaging. However, this imaging technique can suffer from poor signal-to-noise ratio, as the complexity of biological tissues can lead to overlapping of Raman bands from tissues and the Raman reporter molecule utilized.

Measuring the deviation from the superposition principle in interference experiments
New Journal of Physics, 2018 The Feynman path integral formalism has long been used for calculations of probability amplitudes. Over the last few years, it has been extensively used to theoretically demonstrate that the usual application of the superposition principle in slit based ...

A new Raman technique of superior spectral resolution [PDF]
, 1982 Raman-active vibrational modes are coherently excited by the transient stimulated Raman process. A subsequent delayed probe of relatively long duration interacts with the freely relaxing vibrations.
