The beam intensity can be rewritten as WebGaussian beams. The intensity profile of the Bessel beam may offer routes to ... order Bessel functions (n40), the high-order Bessel Beams (HOBBs), have a phase singularity on the beam axis and hence have a non-diffracting dark, rather than bright, core [9]. The intensity profile for a first-order Bessel beam is
WebThe Gaussian beam, like every electromagnetic wave solution, shows diffraction effects. ... The Gaussian beam’s expansion is evident from the increase of its beam waist w(z) as function of zin Eq.
