Partially coherent beams with a prescribed phase, state of polarization, and degree of
coherence display many extraordinary propagation properties and are preferred in many …

Using the extended Huygens–Fresnel principle, a cross-spectral density formula was
developed for a Gaussian Schell model vortex (PCGSMV) beam diffracted through a …

The intensity distribution of a partially coherent beam with a nonconventional correlation
function, named the multi-Gaussian Schell-model (MGSM) beam, focused by an axicon was …

An improved iterative approach is proposed to design a diffractive axicon with long focal
depth and high lateral resolution. Model designs of the diffractive axicon are carried out in …

Using the extended Huygens-Fresnel principle, a cross-spectral density formula was
developed for a Gaussian Schell model vortex (PCGSMV) beam diffracted through …

Theoretically, we have investigated the propagation of fully and partially coherent flat-topped
multi-Gaussian beams through classical and logarithmic axicons. The stationary phase …
