Random pulse source with the temporal multi-complex degree of coherence
Results in Physics, 2023 Based on the coherence theory, the non-stationary optical fields with the complex degree of coherence (CDOC) are expanded from stationary fields, and random pulse sources with temporal multi-complex degree of coherence (TMCDOC) is introduced. Theoretical

Frontiers in Physics, 2022 The spectra of narrow linewidth fiber amplifiers are closely related to both the stimulated Brillouin scattering (SBS) threshold in power scaling process and the combining efficiency in coherent beam combining (CBC) system.

Linear Combinations of the Complex Degrees of Coherence [PDF]
Photonics, 2021 We propose a method for structuring the spatial coherence state of light via mixed linear combinations of N complex degrees of coherence (CDC) and specify the conditions under which such combinations represent a valid CDC.

Sources for random arrays with structured complex degree of coherence
Optics Letters, 2018 Simultaneous control of the far-field spectral density distribution, together with the modulus and the phase of the complex degree of coherence of a beam radiated by a stationary source, is hard to achieve in view of the intrinsic constraints on the source cross-spectral density.

Optics LettersThe van Cittert–Zernike theorem states that the Fourier transform of the intensity distribution function of a distant, incoherent source is equal to the complex degree of coherence. In this Letter, we present a method for measuring the complex degree of coherence in one shot by recording the interference patterns produced by multiple aperture pairs ...

Coherence properties of supercontinuum quantified by complex degree of self-coherence
Acta Physica Sinica, 2012 The complex degree of self-coherence is introduced to quantify the coherence of supercontinuum generated by the same long pulse, and experiments are performed. The coherence properties of supercontinuum generated in the photonic crystal fiber pumped by 700 ps pulse are measured using the Mach-Zehnder interferometer.

Revealing synchrony in pea plants using wavelet coherence analysis [PDF]
Scientific ReportsIn this study, we apply Wavelet Transform Coherence (WTC) analysis—a time–frequency method commonly used in human and animal synchrony research—to examine whether co-potted pea plant dyads exhibit synchronized movement during tendril approach to ...

IOP Conference Series: Earth and Environmental Science, 2020 Abstract The article substantiates the urgent need to assess the coherence degree of production, industrial and food security in the framework of the state agricultural development program implementation. The authors combine two approaches to assessing industrial and production security, and also the processes of ensuring industrial ...

Determination of a source’s temporal coherence function via depolarization in liquid crystal [PDF]
EPJ Web of Conferences, 2022 Based on the fact that the degree of polarization of a light source is given in terms of the absolute value of its complex degree of coherence, we design a depolarization experiment using a variable retarder in which we measured the degree of ...

Propagation Properties of Generalized Schell-Model Pulse Sources in Dispersive Media
Photonics, 2023 A model of a generalized pulse source, whose complex degree of temporal coherence is described by a function of the nth power difference of two instants, was constructed.
