Abstract: The invention relates to a device for the treatment for the surface of a material by depositing a material in powder form comprising:at least one optical fibre (2),a light source (4) able to produce a pulsed light,means (6) for injecting light into a first end of the optical fibre,a miniaturized photoionic head (8) fixed to a second end of the optical fibre and ensuring the diffusion of the light propagated by the optical fibre towards the material to be deposited anda powder reservoir (28a) and a gas reservoir (28b), which are concentric and positioned around the optical fibre and issuing into a dispersion chamber (26) anda confinement ring (16) having two nozzles positioned between the photoionic head and the material to be treated in order to ensure the ionization of the dispersed powder.

Abstract: A backup apparatus for an electronic circuit or part which is installed in a location where access is difficult. The apparatus includes a photoconnector that treats a component by a deposition of a material or by ionic implantation. The photoconnector includes a first light source for generating pulsed luminous energy and a first optical wave guide which has one end connected to the light source. A second light source is attached to the second end of the optical wave guide to receive the luminous energy emitted by the first source and transform it into a shockwave. At least one miniaturized photoionic head is associated with the second light source and diffuses the light supplied by the second light source. An automatic system controls emissions of luminous energy transmitted by the first light source along the optical wave guide.
