The set of diffractive optical elements for CO2 and Nd-Yag lasers was theoretically calculated, fabricated by micro-lithographic technology and experimentally tested. It is shown that the laser systems for therapy, surgery and welding gain from advanced capabilities of the DOEs: uniform focal-spot intensity, simultaneous formation of focal line contours,s harp and multiple-spot focusing, dual-wavelength achromatization, miniaturization.
