Elliptical Laguerre-Gaussian correlated Schell-model beam

Propagation 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...

Multiple 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...

Propagation factor of a stochastic electromagnetic Gaussian Schell-model beam.

Analytical formula is derived for the propagation factor (known asM(2)-factor) of a stochastic electromagnetic Gaussian Schell-model (EGSM) beam in free space and in turbulent atmosphere. In free space, the M(2)-factor of an EGSM beam is mainly determined by its initial degree of polarization, r.m.s. widths of the spectral densities and correlation coefficients, and its value remains invariant ...

Ghost imaging with twisted Gaussian Schell-model beam.

Based on the classical optical coherence theory, ghost imaging with twisted Gaussian Schell-model (GSM) beams is analyzed. It is found that the twist phase of the GSM beam has strong influence on ghost imaging. As the absolute value of the twist factor increases, the ghost image disappears gradually, but its visibility increases. This phenomenon is caused by the fact that the twist phase enhanc...
