摘要： An unstable optical cavity for laser beams, having at least 3 deflection means for making a beam created in the cavity undergo at least three changes in direction so to form an optical ring path, and an optical magnification set disposed among the deflecting means. The at least 3 deflection means are prisms, each of which has an air-glass reflecting interface that provides one of the changes in direction by total reflection. A first of the at least 3 prims is positioned at an output of the cavity and has an air-glass reflecting interface with an insufficient size for a total reflection of the beam in the cavity, and remaining ones of the prisms have an air-glass reflecting interface with a sufficient size for a total reflection of the beam in the cavity.

摘要： The invention relates to a laser active optronic system with improved detectivity, especially an eye-safe optronic system. The system comprises a channel for the emission by an emission source of a laser beam illuminating a target and a channel for receiving the wave backscattered by the target. An optical switching device is positioned in the receive channel, said optical switching device receiving said backscattered wave and comprising an optical gain medium and pumping means for pumping said gain medium, said gain medium being absorbent at the wavelength of the laser and becoming substantially transparent when it is pumped, in such a way as to allow the switching device to be actuated in the on mode or off mode respectively. It further includes a control unit for controlling the pumping means, allowing the switching device to be actuated in the on mode in at least one temporal window of predetermined duration, triggered at a predetermined instant after the start of emission of the illuminating laser beam.

摘要： The field of the invention is that of power lasers pumped by coherent optical sources, such as laser diodes. The aim of the invention is to provide a structure of illumination of a laser rod enabling both efficient removal of the calories released by the coherent optical pumping sources and high homogeneity of the rod pumping operations. The structure is characterized in that the optical sources of at least one set of optical sources are arranged on one and the same delocalized support and in that said structure comprises reflecting means for the transmission, towards the rod, of the illumination beam from said set of delocalized optical sources.

摘要： A quantum well electromagnetic wave detector disclosed having a semiconductor structure including a stacking of layers of material wherein the widths of the forbidden gaps of the materials are used to obtain a profile of potential energy corresponding to the bottom of the conduction band for the electrons in such a way that a first layer has a relatively low energy level with second and third layers having an intermediate energy higher than the energy of the first layer and fourth and fifth layers having high energy greater than either the intermediate or the low energy levels. The energy corresponding to a first permitted level is lower than the potential energy at the bottom of a conduction band of both of the materials used to make the second and third layers and the energy of the second level is between the potential energy at the bottom of a conduction band of both materials of the second and third layers and the potential energy of the bottom of the conduction band of the materials of the fourth and fifth layers. The first permitted level of energy of the quantum well is populated with electrons and an electric field is applied perpendicular to the plane of the structure.
