Paper Abstract

The set of diffractive optical elements for CO2 and Nd- Yag lasers was theoretically calculated, fabricated by microlithographic 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, sharp and multiple-spot focusing, dual-wavelength achromatization, miniaturization. Novel multifocal diffractive contact lenses are elaborated based on diffractive microrelief considerations, nonparaxial variant of diffraction integral on curved surface and computer simulations of intensity distribution on eye retina. Tri- focal diffractive contact lenses that were diamond-turned on rigid and soft materials successfully passed tests.
