Abstract

To overcome the limitation of the current memories some authors developed method for storing data throughout a volume of memory material using two-photon absorption effect. In this work we represent the three-dimensional vector analysis of diffraction laser beam by the simple model of this volume data storage. We represent the volume data storage as homogeneous dielectric in which three- dimensional grating of spheres with complex (epsilon) , (mu) are located. To evaluate scattering field of partial wave we used Lorenz-Mie theory. The total scattering field is sum of partial scattering fields and some small addition field of re-radiation. The addition field of re-radiation was evaluated in first approach of perturbation theory. The investigation results were used for the determination of recording information limits into the memory material.
