Diffraction is a phenomenon related to the wave nature of light and arises when a
propagating wave comes across an obstacle. Consequently, the wave can be transformed in …

Optical coherence is a fundamental characteristic of light that plays a significant role in
understanding interference, propagation, light–matter interaction, and other fundamental …

In this paper, we introduce a new kind of vector multi-Gaussian Schell-model (MGSM) beam
named radially polarized MGSM beam as an extension of recently introduced scalar MGSM …

A partially coherent beam called a radially polarized multi-Gaussian Schell-model power-
exponent-phase vortex beam is introduced. Both the analytical formula of the beam …

Focusing of a vectorial (electromagnetic) optical beam through a high numerical aperture
can be investigated by means of the Richards–Wolf diffraction integral. However, such an …

We show that it is possible to generate transversely random, diffraction-free/longitudinally
invariant vector optical fields. The randomness in transverse polarization distribution …

In this paper, the propagation characteristics of adjustable anomalous hollow Gaussian
beams are investigated in different cascaded systems composed of left-handed medium and …

Abstract Based on the Richards–Wolf vectorial diffraction theory, the tight focusing
properties, including the intensity distribution, the degree of polarization and the degree of …

Propagation properties of high-power fiber laser with high-order-mode (HOM) content are
studied numerically for the first time to the best of our knowledge. The effect of HOM on the …
