Optimal Coherence Length Control in Interferometric Fiber Optic Hydrophones via PRBS Modulation: Theory and Experiment [PDF]

open access: yesSensors
Interferometric fiber optic hydrophones (IFOHs) are highly sensitive for underwater acoustic detection but face challenges owing to the trade-off between laser monochromaticity and coherence length.

On coherence lengths of wave packets [PDF]

open access: yesProgress of Theoretical Physics, 2009
Coherence lengths of one particle states described by quantum wave functions are studied. We show that one particle states in various situations are not described by simple plane waves but are described by wave packets that are superpositions of plane ...

Coherence lengths and anisotropy in MgB2 superconductor [PDF]

open access: yes, 2002
Field and temperature microwave measurements have been carried out on MgB2 thin film grown on Al2O3 substrate. The analysis reveals the mean field coherence length xi_{MF} in the mixed state and a temperature independent anisotropy ratio gamma_{MF} = xi_{

Cylinder aeroacoustics: experimental study of the influence of cross-section shape on spanwise coherence length

open access: yesActa Acustica, 2023
New data and review of the spanwise coherence length is provided for flows over cylinders of different cross-sections: circular of diameter d, and rectangular of sectional aspect ratios (breadth (b) to height (d) ratio AR = b/d) of 1, 2 and 3.

Dependence of spectral characteristics of semiconductor and solid state lasers of visible range on active environment temperature [PDF]

open access: yesНаучно-технический вестник информационных технологий, механики и оптики, 2018
We consider research results on the effect of the active medium temperature, which varies with the operation of semiconductor and solid-state (DPSS) lasers of the visible range, on the output spectral characteristics. The paper presents the study results

The Role of the Short Coherence Length in Unconventional Superconductors

open access: yesCondensed Matter, 2020
A short coherence length is a distinctive feature of many cases of unconventional superconductivity. While in conventional superconductors, it is many orders of magnitude larger than the basic inter-particle distance, a short coherence length is common ...

Superconducting Stiffness and Coherence Length of FeSe0.5Te0.5 Measured in a Zero-Applied Field

open access: yesCondensed Matter, 2023
Superconducting stiffness ρs and coherence length ξ are usually determined by measuring the penetration depth λ of a magnetic field and the upper critical field Hc2 of a superconductor (SC), respectively.

Beam Properties of a Partially Coherent Beam Propagating Horizontally in Atmospheric Turbulence

open access: yesPhotonics, 2023
This study explored the impact of atmospheric turbulence on partially coherent light propagation. Atmospheric turbulence causes random modulation of the intensity and phase of light, resulting in a speckle pattern in the far field.
