Abstract

A coherent optical method and concept are presented for the generation of an intense, very precisely spaced 2-D array of laser beams which maintain their relative position over significant distances. The array is achieved through the use of a recently invented quadriprism.1 A signal pattern encoded on a 128x128 array has been precisely transported over several meters. An attractive feature of the system is the low optical energy in the array interstitial space. The interposing of grids or arrays of rectangular lattice electrodes yields very low diffraction losses, thereby making the beam array ideal, e.g., in pipeline processors. Some conceptual applications are discussed.
