Propagation Behavior Of Partially Coherent General Model Vortex Higher-Order Cosh- Gaussian Beam In Biological Tissues

Analytical expression for a partially coherent General Model vortex higher-order cosh-Gaussian beam (PCGMvHchGB) propagating in biological tissue medium is derived using extended Huygens-Fresnel method. Propagation characteristics of the PCGMvHchGB passing through biological tissue are discussed by some numerical results. The results indicate that the the PCGMvHchGB evolution is highly dependent on source beam parameters, including the spatial correlation length, decentered cosh and hollowness parameters, wavelength and orders of beam. Notably, the PCGMvHchGB in biological tissue transitions into a Gaussian beam more rapidly with smaller source parameters and further increasing propagation distance. This observation suggests that the resistance of PCGMvHchGB against turbulence is augmented with larger beam parameters. The significance of our findings lies in their potential applications in imaging technologies and bio-optical disease diagnosis.
