Paper Abstract

A new model is applied to describe the field distribution at the output of the LDAs. Formalism describing of the far-field radiation patterns of a laser arrays is presented, base on rigorous solutions of the Helmholtz equations. The beam-divergence angles normal and parallel to the junction plane are concluded. Theoretical results presented are in close agreement with the experiments. and the final result is expressed in a form convenient for diffraction analysis of LDAs beams.
