Abstract: Gluing process for micro-structured substrates. The invention is applicable particularly to the fabrication of micro-fluidic components. In order to glue a micro-structured substrate having upper coplanar plane areas and recesses between them, a grid is placed above the substrate, the grid is coated with a glue, using a tool that presses on the grid and locally brings it into contact with the areas, so as to deposit a film of glue droplets on them, and the grid is removed. Furthermore, the upper coplanar plane areas are treated before the film of glue droplets is deposited, this treatment being designed to adapt wettability of these areas to the glue.

Abstract: The invention relates to a thermoelectric means (60) that can be woven or knitted, taking the form of an elongate body and having on its surface at least one converter for converting thermal energy into electrical energy. The invention also relates to a structure for converting a temperature difference over the thickness of the structure into electricity, which consists of an assembly formed by the interlacement of textile fibers (8), of said thermoelectric means (60) and of connection means (7).

Abstract: Gluing process for micro-structured substrates. The invention is applicable particularly to the fabrication of micro-fluidic components. In order to glue a micro-structured substrate (2) having upper coplanar plane areas (6) and recesses between them, a grid (10) is placed above the substrate, the grid is coated with a glue (12), using a tool (16) that presses on the grid and locally brings it into contact with the areas, so as to deposit a film (20) of glue droplets on them, and the grid is removed. Furthermore, the upper coplanar plane areas (6) are treated before the film of glue droplets is deposited, this treatment being designed to adapt wettability of these areas to the glue.

Abstract: A laser cavity with passive switching by a saturable absorber and a laser incorporating the cavity. The laser cavity has a solid, active material saturable absorber, an entrance mirror and an exit mirror. The saturable absorber is a thin film of saturable absorber material directly deposited on the solid, active medium. The laser incorporates such cavity and a mechanism for pumping the cavity.

Abstract: Optically pumped laser minicavity, its production process and laser using said cavity, wherein the minicavity comprises an electrically insulating, parallelepipedic, solid emitter (1b), having two polished parallel lateral faces (6, 8), a monocrystalline substrate (2) and several monocrystalline layers epitaxied on the substrate and having in directions parallel to said faces a hardness equal to that of the substrate, one of the layers constituting a guide layer (4) able to guide the light emitted by the emitter and the pumping light and another layer (12) constituting a non-guiding protective layer, the protective layer and the substrate constituting two opposite faces of the emitter perpendicular to the lateral faces, laser activating ions being contained within the substrate and/or in one of the layers. In the case of an internal cavity, semi-reflecting mirrors (9, 10) are placed on the lateral faces of the emitter.
