Abstract

Based on the numerical solution of the parabolic wave equation for the complex spectral amplitude of the wave field the propagation of a short pulsed Laguerre–Gaussian beam with femtosecond duration was studied. It has been shown that the diffraction broadening of the Laguerre–Gaussian beam decreases with the pulse duration in comparison with continuous-wave radiation.
