Impact of Human upper Dermis tissue on the spectral intensity of a pulsed chirped General Model vortex higher-order cosh-Gaussian beam

Abstract

Abstract We conduct the analytical study of the propagation properties of a pulsed chirped General Model vortex Higher-order cosh-Gaussian beam (GMvHchGB) passing through human upper dermis tissue using the power spectrum refractive index, the extended Huygens-Fresnel integral, and the Fourier Transform method in this study. We perform numerical simulations based on the derived formula to illustrate how the properties of this beam are affected by varying beam parameter configurations within the human upper dermis tissue. We observe that the pulsed chirped GMvHchGB undergoes changes in its shape as it traverses a considerable distance through this medium. In the numerical analysis, we focus on the impact of incident parameters such as Gaussian waist, cosh parameter, hollowness, and beam order. We anticipate that the results obtained from our simulations are significant in developing bio-optical disease detection and treatment technologies especially for cancer. Based on the difference in the intensity distribution, scientists can detect the diseases.
