| Abstract: | The modulation diffraction rings of a intense laser beam propagation in linear medium is investigated numerically by a two-dimensional fast Fourier transformation algorithm. The definition for Fresnal number in linear mediums is given on the basis of the properties of the diffraction rings land the relationship between the number of diffraction rings and Fresnal number is obtained. |
