Abstract: The invention concerns a device comprising on a substrate (2) a stack including an etching boundary layer (6), a first barrier layer (10), an emitting layer (8) and a second barrier layer (12). The boundary layer is of the same type as the emitting layer. A mirror can be formed on the stack, the substrate eliminated by etching and another mirror formed on the boundary layer to obtain a micro-cavity. The invention is particularly applicable to gas detection.

Abstract: The invention relates to a cryostat (1) for studying samples in a vacuum. This cryostat comprises a cold finger (2) provided with a finger part (5) as well as with a finger base (10) connected to the finger part. The cryostat also comprises a sample carrier (32) mounted at an end of the finger part that is free from cooling, this finger part being placed in a vacuum enclosure (4). This vacuum enclosure is partially delimited by a hollow part (6) consisting of a single piece and defining an open cavity (46) with a single opening (44) through which the finger part passes. The sample carrier is located inside this open cavity (46). The enclosure is also delimited by a cryostat body (8) whose cylindrical outer surface (36) with a circular cross-section interacts with a device (62) for rotating.

Abstract: The invention relates to a device for optical pumping radiation emission comprising light emitting means (19) provided with a first resonant cavity having a first input mirror and an output mirror, optical pumping means (21) for emitting a pumping beam of the first cavity, wherein the normal to the input face of the resonant cavity is inclined at an angle υ with respect to the propagation direction of the pumping beam (20), means for forming a second pumping beam resonant cavity, wherein said means comprises a second input mirror forming said second cavity with the output mirror of the first cavity. The inventive device is characterised in that it comprises an optical element transparent to the pumping wavelength between the first and second input mirrors.
