Optical detection, measurement, and treatment methods are widely used in the medical industry nowadays. The evolution of radiated beams, received power and beam size play vital roles while developing devices. The propagation properties of hollow higher-order cosh-Gaussian beam (HHOCGB) while propagating in human upper dermis tissue are derived analytically and analyzed numerically. The impact of the hollowness parameter, beam order, operating wavelength, and Gaussian beam waists on the beam’s intensity profile is examined. Received power and beam size variations are analyzed considering operating wavelength and Gaussian waist width. According to the results, as the beam propagates, its profile rapidly evolves into a shape with a circular Gaussian peak in the center and petals at the corner. Dark hollow regions are observed among the petals. Furthermore, the received power by HHOCGBs with a higher Gaussian waist width is more than those received by beams with a lower Gaussian waist width. However, at far field, operating at a lower wavelength prevents the increase of the beam spread. Thus, the obtained results will be significant in the bio-optical disease detection and treatment technology development.

The purpose of this paper is to explore the evolution behavior of two important laser features: the Bessel higher-order cosh-Gaussian (BHoChG) beam and the Bessel higher-order sinh-Gaussian (BHoShG) beam propagating through turbulent oceanic environments. Benefiting from the extended Huygens-Fresnel principle, the analytical formulas for the average intensity of the beams passing through oceanic turbulence are derived. The propagation of some laser beams through oceanic turbulence is also deduced as particular cases from the present study. The effects of oceanic turbulence parameters and the source beam parameters are examined to understand their influence on the intensity distribution of the considered beams by using numerical simulations. Our results show that the spreading of these beams depends on their initial parameters and oceanic parameters. Hence, the propagation of the studied beams through oceanic turbulent will be faster with the smaller dissipation rate of the mean square temperature, larger salinity fluctuations, higher rate of dissipation of turbulent kinetic energy per unit mass of fluid and with decreasing the beam width and the parameter Ω. The outputs of this study have useful applications in optical underwater communication, remote sensing, imaging and others.

This paper aims to study the evolution behavior of Generalized Hermite cosh-Gaussian beam (GHCGB), when it propagates through a turbulent oceanic medium. Extended Huygens-Fresnel principal is used to evaluate the received intensity expression for the considered beam propagating in oceanic turbulence. Numerical examples are analyzed to illustrate the variations of average intensity under the influences of the oceanic turbulence parameters and the source beam parameters. Results show that the GHCGB propagating in stronger oceanic turbulence will lose its first profile and evolve into a Gaussian distribution rapidly with the larger dissipation rate of mean squared temperature and relative strength of temperature and salinity fluctuations or the smaller rate of dissipation of turbulent kinetic energy per unit mass of fluid, in the far field. According to the provided study, the results obtained are useful to the practical application of the GHCGB in oceanic turbulence for both imaging systems and underwater optical communication.
