Magnetic Field Dependence of Spectral Correlations between 31P-Containing Metabolites in Brain

open access: yesMetabolites, 2023
Spectral correlations between metabolites in 31P magnetic resonance spectroscopy (MRS) spectra of human brain were compared at 3 and 7 Tesla, the two commonly used magnetic field strengths for clinical research. It was found that at both field strengths,

The Variation of the Linewidths and Amplitudes of Sub-Doppler Resonances of 87Rb D2 Line with Laser Beam Intensity

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2022
The sub-Doppler resonances linewidths and amplitudes depend on the laser beam intensity. The effect of laser beam intensity on the resonance linewidths and amplitudes obtained from different energy transitions of atoms varies from resonance to resonance.

High-power free-running single-longitudinal-mode diamond Raman laser enabled by suppressing parasitic stimulated Brillouin scattering

open access: yesHigh Power Laser Science and Engineering, 2023
A continuous-wave (CW) single-longitudinal-mode (SLM) Raman laser at 1240 nm with power of up to 20.6 W was demonstrated in a free-running diamond Raman oscillator without any axial-mode selection elements.

Determining the Stable Injection Locking of a Fabry-Pérot Laser by Observing the RF Spectral Components Generated by a Low-Reflectivity External Cavity

open access: yesPhotonics, 2021
A novel approach to monitoring the laser injection-locking (IL) state is proposed and verified using the side-mode suppression ratio (SMSR). In a photonics experiment for laser IL, an optical spectrum analyzer with the conventional criterion of a 35-dB ...

Revealing of Li-Ion Transportation in Crystal Lattices by 7Li SAE in Solid-State NMR

open access: yesChinese Journal of Magnetic Resonance, 2020
Spin alignment echo (SAE) is employed here to study the α-LiAsF6/PEO6 system with low poly(ethylene oxide) (PEO) molecular weight. We show that the correlation rate kSAE from SAE experiments, but not the spin-lattice relaxation time and the linewidth, is
