A study of the comparison of some laser beams spreading through human and mouse biological tissues

Abstract

Aiming at the Bessel higher-order cosh-Gaussian (BHoChG) beam and the Bessel higher-order sinh-Gaussian (BHoShG) beam, we investigate their propagation properties through turbulent biological tissues. In this respect, the analytical expression of the considered beams is obtained and developed, based on the extended Huygens-Fresnel integral. By numerical simulation, the intensity distributions of these beams for biological tissue types including intestinal epithelium and deep dermis of mouse in addition the human upper dermis versus the propagation distance as a function of the variations of the laser beam parameters. The obtained results indicate that the resistance of our beams against turbulent biological tissues increases as the source parameter increases counting the decentered parameter, the beam-order of the considered beams and the beam waist width. The findings show that the intensity distribution of the propagation of these beams occurs more quickly when they pass through the deep dermis of the mouse. The results presented in this paper are significant due to their potential application in determining the deterioration or disruption of biological tissue, medical imaging and medical diagnosis.
