The experiments were performed for sodium atom deposition on a sapphire substrate. The sapphire substrate was illuminated through a commercial linear mire with a pitch of 10 µm by a 440 nm laser beam with 1W/cm2 intensity. This provides the nonuniform spatial distribution of the illumination intensity over the sapphire surface and optical control of sodium atom deposition on the sapphire substrate, preventing the nucleation and growth of the granular ﬁlm in the illuminated areas. Experiments showed that the mire pattern was well reproduced in the sodium deposits, thus creating the microstructured metallic ﬁlm with few tens nm thickness. The novel suggestion to use nondiﬀracting optical beams for high contrast microstructuring of surface metal ﬁlm is presented.</p></abstract><kwd-group xml:lang="en"><kwd>metal nanoparticle</kwd><kwd>adsorption</kwd><kwd>desorption</kwd><kwd>laser controlled growth</kwd><kwd>non-diffracting optical beams</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>The financial support from EU project LIMACONA (IRSES-GA-2013-6126000) and from Government of Russian Federation (Grant 074-U01) is gratefully acknowledged.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">S.Y.Lin, J.G.Flemming, D.C.
