Abstract
We analyze the properties of diffraction focusing systems composed of a series of irises, coaxially distributed along a laser beam. Based on diffracted-ray methods, complete design equations and optimization procedures are given. Focusing experiments on a He-Ne laser beam are reported with two types of focusing structures, and the results agree completely with the theoretical predictions.
