Focus shaping of the radially polarized Laguerre-Gaussian-correlated Schell-model vortex beams

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 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...

Experimental Method of Generating Electromagnetic Gaussian Schell-model Beams Thesis

Z-scan experiment with anisotropic Gaussian Schell-model beams.

We analyze the z-scan experiment with anisotropic Gaussian Schell-model (AGSM) beams. The expression for the cross-spectral density of the AGSM beam passing through the lens and onto the nonlinear thin sample is derived. Based on the expression, we simulate the results of the z-scan experiment theoretically and analyze the effects of the e factor (e=w(0x)/w(0y)) and the spatial degree of cohere...
