Computer generated diffractive optical elements, known as $quot;focusators$quot;, provide for very complicated focal intensity distributions, depending on the number of pixels and quantization levels. The manufacturing of such elements is very expensive and must be preceded by computer simulation of their performance. Computer experiment with laser beam focusator into segments is described in this report, the estimations of power efficiency and focal line quality for various parameters of the phase digitization are obtained.
