Generation of inhomogeneously polarized laser beams of high order by means of diffractive optical elements

Astigmatic transformation of one dimensional distributions, such as Airy functions, is considered. Various types of astigmatic converters, including one cylindrical lens are considered. As a result of such transformations it is possible to form matrices of optical vortices of a various configuration, which, in particular, expands possibilities of an optical micromanipulation. Results of modelling and natural experiments are discussed.
