Paper Abstract

The statistical properties of three-dimensional light scattering fields produced by two or three random optical waves propagating in the directions orthogonal to each other are studied theoretically. As a result of the interference of crossed speckle fields, spatial anisotropy of intensity distributions, which exists in a three-dimensional single speckle field, is almost eliminated. It is found that the resultant field has a random intensity distribution in a macroscopic scale, but it has a periodic spatial structure in a microscopic scale. The possibility of making a new type of random lasers with the use of photopolymers and the crossed scattering fields is shown.
