Airborne water vapor DIAL system and measurements of water and aerosol profiles [PDF]
The Lidar Applications Group at NASA Langley Research Center has developed a differential absorption lidar (DIAL) system for the remote measurement of atmospheric water vapor (H2O) and aerosols from an aircraft.

Advanced Physics Research, EarlyView.This study presents toroidal‐dipole (TD)‐driven polarisation‐selective quasi‐bound states in the continuum (quasi‐BICs) in all‐dielectric metasurfaces, enabling transverse magnetic (TM)‐selective excitation with ultrahigh quality factors and wide‐angle‐stable polarisation‐dependent near‐field imaging.

High-power, ultra-low-noise cascaded diamond Raman lasers with spectrum compression
High Power Laser Science and EngineeringStimulated Raman scattering is a third-order nonlinear optical effect that is not only effective for wavelength converting laser output, but also for single longitudinal-mode output due to the absence of spatial hole burning. Diamond is a prominent Raman-

Battery Energy, Volume 4, Issue 2, March 2025.The effect of reagents on the structure and performance of sodium‐layered oxides has not yet been thoroughly studied. This work explored this factor systematically through in situ high‐temperature XRD. The samples synthesized via MnCO3‐based precursors form the Li2MnO3 phase at evaluated temperature and perform better than those through MnO2‐based ...

Monolithic narrow-linewidth InGaAsP semiconductor laser for coherent optical communications [PDF]
A design for a monolithic narrow-linewidth InGaAsP diode laser has been developed using a multiple-quantum-well (MQW) extended-passive-cavity distributed-Bragg-reflector (DBR) laser design.

Optimization of CEST MRI Reporter Protein Design Using Cation‐Pi Networks
Chemistry – A European Journal, EarlyView.A novel engineering approach can produce reporter proteins for cell and viral therapy tracking with unique magnetic resonance imaging (MRI) signatures, detectable with chemical exchange saturation transfer (CEST). We discover how cation‐π interactions between amino acid groups can help us fine‐tune magnetic resonance properties for noninvasive ...

High Spectral Purity, Narrow Linewidth Laser Transmitter for Dial Measurements [PDF]
A laser transmission with very high degree of spectral purity was described. Amplified Spontaneous Emission (ASE) dependence on the oscillator energy and the detuning away from the gain curve center are demonstrated.

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.The correlation of a spectroscopic (EPRI) and microscopic (AFM) technique is demonstrated for a sample of Li deposited on Cu. Areas of different morphology were analysed. The techniques complement each other's length scales as well as the information obtained from the sample.
