Solutions of the parabolic equation which describes propagation of Bessel–Gaussian beams along the axis of an axially-symmetric medium having quadratic inhomogeneity have been obtained and investigated. It is shown that in the process of propagation the parameters of the beams change nonmonotonically. ...
Furthermore, high-power Bessel–Gaussian beams with both active and passive arrangements are set up. The experimental results verify the validity of the theoretical model and the accuracy of the selected parameters. In this paper, an effective guideline is presented for designing more efficient, ...
Bessel-Gaussian beamshard-aperture misaligned optical systempropagationIn this paper, we consider the propagation of high-order Bessel–Gaussian beams (HBGBs) passing through a hard-aperture misaligned optical system. By expanding the hard-aperture function into a finite sum of complex Gaussian ...
Based on the second-order irradiance moment definition, a closed-form expression for the beam width of Bessel-modulated Gaussian beams (QBG beams) is derived, from which the expressions for the waist width, its position, and beam propagation factor (M 2 factor) of QBG beams with complex ...
In previous works, efforts have been made to clarify whether Bessel or Gaussian beams are more suitable for wireless power transfer. However, the theoretical discussions proposed so far did not attract a general consensus from the community, the arguments often being based on restrictive, arbitrary ...
Based on the truncated second-order moments method on the cylindrical coordinate systems and the incomplete gamma function, an analytical expression of the generalized beam propagation factor ( M G 2 factor) of hard-edged circular apertured diffracted Bessel–Gaussian beams is derived and illustrated ...
