Abstract

The estimation of performance of computer-generated optical elements (CGOE) at the design stage is the actual task. In this paper the mathematical model of laser beam focusing by CGOE is suggested. On the basis of this model, the following results have been obtained: a numerical method for the diffraction computing of the field at the focal region, and also algorithms and software for investigating diffraction characteristics of focusators within the scope of computer simulation. The estimations of power efficiency, focal line width, and light intensity distribution at a focal region for various types of focusators vs physical parameters, number of samples, and number of quantization levels are obtained as a result of computational experiments. CGOE with an elevated depth of focus and focusator at semi-ring are investigated.
