Abstract:
This paper considers the propagation of pulsed optical Gaussian beams through a homogeneous medium under different diffraction conditions on a transmitting aperture. It is shown that for any curvature radius of the initial wave front the diffraction broadening of a pulsed beam decreases with a decrease in the pulse duration, and in the limiting case of zero pulse duration the diffraction spreading of a pulsed beam is absent.
