Propagation factors of cosine-Gaussian-correlated Schell-model beams in non-Kolmogorov turbulence.
Based on the extended Huygens-Fresnel principle and second-order moments of the Wigner distribution function (WDF), we have studied the relative root-mean-square (rms) angular width and the propagation factor of cosine-Gaussian-correlated Schell-model (CGSM) beams propagating in non-Kolmogorov turbulence. It has been found that the CGSM beam has advantage over the Gaussian Schell-model (GSM) be...
متن کاملMultiple optical cages generated by focusing a Laguerre-cosine-Gaussian correlated Schell-model beam
We introduce a new kind of random stationary, scalar beam named Laguerre-cosine-Gaussian correlated Schell-model (LcGCSM) beam whose spectral degree of coherence (SDOC) is a Gaussian function modulated by both non-conventional Laguerreand cosine-type factors. The analytical expressions for the cross-spectral density of a LcGCSM beam propagating through a paraxial ABCD optical system are derived...
متن کاملPropagation properties of Laguerre-Gaussian correlated Schell-model beam in non-Kolmogorov turbulence.
Analytical formulas are derived for the average intensity, the root-mean-square (rms) angular width, and the M2-factor of Laguerre-Gaussian correlated Schell-model (LGCSM) beam propagating in non-Kolmogorov turbulence. The influence of the beam and turbulence parameters on the LGCSM beam is numerically calculated. It is shown that the quality of the LGCSM beam can be improved by choo...
متن کاملWander and Spreading of Gaussian-Schell Model Beams Propagating through Anisotropic Marine-Atmospheric Turbulence
The effects of anisotropic turbulence on the wander and spreading of Gaussian-Schell model beams propagating in non-Kolmogorov marine-atmospheric channel are investigated. Expressions for beam wander and long-term beam spreading are derived in all conditions of marine-atmospheric turbulence. Our results indicate that the beam wander and spreading of Gaussian-Schell model beams are lower in the ...
متن کاملAverage Polarization of Electromagnetic Gaussian Schell-Model Beams through Anisotropic Non-Kolmogorov Turbulence
Polarization properties of electromagnetic Gaussian Schell-model beams propagating through the anisotropic non-Kolmogorov turbulence of marine-atmosphere channel are studied based on the cross-spectral density matrix. Detailed analysis shows that the average polarization decreases with increasing the spectral index, inner scale of turbulence and generalized refractive-index structure parameter....
