Abstract

An IR DOE (the wavelength is 10.6 micrometers ) focusing the Gaussian illuminating beam into a ring of desired width is designed. The phase function of the element is found during 111 iterations of the procedure that relates the problem of focusing into a radial off-axis domain to the problem of focusing into the line-segment.
