The spatial distribution of two-photon excitation created by crossed focused Gaussian beams is shown. The effective volume calculation for the two-photon interaction of crossed Gaussian beams is presented. The dimensions of cubic and parallelepiped volumes, in which half of the two-photon interaction is localized, are determined. The memory densities of two-photon three-dimensional memory for crossed focused beams and one focused beam are compared.
