New units and modified constructional components of an optical channel of a scanning X-Y laser nanolithographer are described. The nanolithographer serves for direct laser writing of subwavelength diffractive structures on thin-film photo- and thermo

Diffractive optics are promising for use in interferometry as a Transmission Sphere (TS) due to the fact that it is simpler and cheaper, since it consists of one component. However, in the manufacture and use of Diffractive TS (DTS) with an aperture

A method is proposed for efficient, rotationally symmetric, tight mirror focusing of laser beams that is optimally matched to their thin-film linear-to-radial polarization conversion by a constant near-Brewster angle of incidence of the beams onto a
