Abstract: The inventive method for forming nano-dimensional clusters consists in introducing a solution containing a cluster-forming material into nano-pores of natural or artificial origin contained in a substrate material and in subsequently exposing said solution to a laser radiation pulse in such a way that a low-temperature plasma producing a gaseous medium in the domain of the existence thereof, wherein a cluster material is returned to a pure material by the crystallization thereof on a liquid substrate while the plasma is cooling, occurs, thereby forming mono-crystal quantum dots spliced with the substrate material. Said method makes it possible to form two- or three-dimensional cluster lattices and clusters spliced with each other from different materials. The invention also makes it possible to produce wires from different materials in the substrate nano-cavities and the quantum dots from the solution micro-drops distributed through an organic material applied to a glass.

Abstract: A method for producing a metallized image on a sheet material includes impregnating the material with a metal salts-containing solution and exposing the specified material points to a pulse laser radiation. The interaction of the pulses with the solution within a laser spot irritates a photochemical reaction resulting in a metal ion reduction into the elementary state thereof by associating the required number of electrons and deposition of metallic film which is firmly fixed to the filler of the sheet material in the laser spot area on the material surface. In case of sufficient laser radiation power, a recess is formed on the sheet material surface, and the metallic film is deposited on the bottom of the recess.

Abstract: The printing machine is designed to print different polygraphic matter without replacement of the printing form upon transition from printing one publication to another. The machine includes a printing form in the form of a mesh, and operates by filling all of the mesh cells with ink and forcing the ink through selected mesh cells by the light-hydraulic effect, which is to heat part of the ink volume in a cell with a laser beam pulse which in turn ejects all of the ink from the cell toward a receiving medium.

Abstract: The method for printing is carried out by creating pressure pulses at individual points of an ink layer which has been applied onto the surface of a continuous smooth plate, focusing a light beam of a laser on those points from the side of the opposite surface of the plate. Pressure pulses are developed due to the light hydraulic effect at the border of the surface of a plate, made of transparent material, and a layer of ink applied thereon, or due to the conversion of light radiation into acoustic when the light beam of the laser is absorbed by material which is not transparent for its wavelength. The printer has a device for deflecting the light beam over the surface of the plate to excite pressure pulses in the ink layer at points predetermined by a program.

Abstract: A method of ink-jet printing is carried out by focusing a light beam from a quantum generator onto an expendable liquid printing material in a jet from the direction of the open end of the jet, with an information carrier placed in front of the open end, in order to generate a pressure pulse ensuring the expulsion of a droplet of the liquid onto the carrier. The method is carried out by directing the light beam onto the material in a jet either at an angle to its surface between the jet and the carrier, or through a carrier which is transparent to the wavelength of the beam. An ink-jet printing head has rows of jets, each with one blind end formed in the body of a driving drum.

Abstract: A printing method is performed with an ink jet print head including a matrix of groups of orifices positioned in parallel rows. Each group has a plurality of orifices which each eject fluid of a different color. The color fluid, e.g. ink, is simultaneously propelled through the orifices of each group selected for printing and onto an information carrier which is stationary in relation to the matrix. The print head has a multilaminate structure with additional layers (20-25) of an underlay (10) equal to the number of print colors. The orifices (BK, Y, R, B) are divided into groups of adjoining orifices with the same number of orifices in each group and with the orifices in each group disposed in a square arrangement. The inlet openings of all orifices which eject fluid of the same color are placed in a single additional layer of the underlay. Feeder channels (26-29) are made in each additional layer of the underlay and cross the orifice openings (11-14) in that layer.

Abstract: A method of growing epitaxial semiconductor films on substrates is proposed which consists in that a substrate is cleaned from damage layers and heated to a critical epitaxy temperature simultaneously by irradiating a substrate surface with an intensive luminous flux. A source material for growing a film is introduced to the substrate in a gaseous state. When producing multi-layer semiconductor structures, a substrate surface opposite to a surface exposed to the luminous flux is cooled to a temperature sufficient to prevent mutual diffusion between the film and the substrate materials. Versions of an apparatus for carrying this method into effect are also proposed. The apparatus includes a quartz chamber with a vaporizer for vaporizing the source material for film growing, a means for supporting the substrate and openings for introducing a neutral or reducing agent. The apparatus is provided with furnaces for heating the walls of the chamber.
