Complex Gaussian representations of partially coherent beams with nonconventional degrees of coherence.
TLDR
The recently introduced complex Gaussian function is adopted to expand the partially coherent beams with nonconventional degrees of coherence, and it is found that the uniaxial crystal can be used to control the splitting properties of a Hermite-Gaussian correlated Schell-model beam.Abstract:
We adopt the recently introduced complex Gaussian function to expand the partially coherent beams with nonconventional degrees of coherence, and derive detailed representations of Hermite–Gaussian correlated Schell-model beam, elliptical Laguerre–Gaussian correlated Schell-model beam, and multi-Gaussian correlated Schell-model beam. Complex Gaussian representation of a partially coherent beam provides a convenient way for treating its propagation. As an application example, we explore the self-splitting properties of a Hermite–Gaussian correlated Schell-model beam propagating in a uniaxial crystal with the help of the complex Gaussian representation, and it is found that the uniaxial crystal can be used to control the splitting properties.read more

Self-steering partially coherent vector beams
TL;DR: It is shown that self-steering partially coherent vector optical beams have mobile guiding centers of their intensity and polarization state distributions on the beam free space propagation that could be employed to generate far-field polarization arrays.
