Abstract
Analytical expressions of second-order intensity moments and factors for a conically refracted (CR) Gaussian beam and its components are derived. for a CR beam is shown to depend on a single parameter, the ratio of the CR ray cylinder radius and the input Gaussian beam waist radius. In typical CR conditions when this ratio is much greater than one, is also much greater than one even though the divergence angle for a CR beam is the same as for the input Gaussian beam. The increased value results from the much larger size of CR beam in the focal plane compared with the waist size of input Gaussian beam. values derived from focal- and Fourier-plane intensity profiles agree with theoretically predicted ones. Second-order moments and factors of a CR beam and its components are compared with those of Gaussian, Laguerre–Gauss, and modified Bessel–Gauss beams.
