摘要： In a stripline laser, a gas mixture containing carbon dioxide CO
2 is situated as laser-active medium between two plate-type electrodes (2, 4) lying with their flat sides (20, 40) opposite one another. The electrodes (2, 4) define a discharge space (5), at whose end sides lying opposite one another a resonator mirror (6, 8) is respectively arranged. The resonator mirrors (6, 8) form an unstable resonator parallel to the flat sides (20,40). In order to be able to operate the stripline laser in the 9.3 μm band and/or in the 9.6 µm band, the electrodes (2, 4) are provided with a passivation layer (10, 12) on their flat sides (20, 40) lying opposite one another, said passivation layer, in the case of at least one electrode (2), containing silicon dioxide SiO
2 in a region (14) covering at least a partial area (22) of the flat side (20), wherein the distance (a) between the electrodes (2, 4) is set in such a way that the attenuation of laser beams in the 10.3 µm band and in the 10.6 µm band is greater than the attenuation of laser beams in the 9.3 µm band and/or in the 9.6 µm band.

摘要： The invention relates to a ribbon laser, in which a laser gas (LG) is present between elongated electrodes, whose flat surfaces lie in pairs opposite one another. Said laser contains a large number of electrode pairs (2a-d) and a respective narrow discharge chamber (3a-d) is formed between each of said pairs. The discharge chambers (3a-d) are optically intercoupled by means of folding reflectors (26) and are positioned adjacent to one another in such a way that the central planes of the discharge chambers (3a-d), running parallel to the flat surfaces of the electrodes, lie on a common plane. At least one waveguide (30) is provided to guide the laser beam between the respective adjacent discharge chambers (3a-d) that are directly intercoupled.

摘要： In a slab laser, a gas mixture containing carbon dioxide CO2 is formed as a laser-active medium in a discharge space which is formed between two plate-shaped metal electrodes, the flat faces of which are located opposite one another. A resonator mirror is arranged on each of the mutually opposite end faces of the discharge space, the mirrors forming an unstable resonator parallel to the flat faces. At least one of the mutually facing flat faces is provided either on the entire flat face with a dielectric layer the thickness of which is greater on at least one sub-surface than in the remaining area of the flat face, or the at least one flat face is provided with a dielectric layer exclusively on at least one sub-surface.

摘要： In a slab or strip conductor laser with mutually parallel electrodes (2, 4) forming a discharge chamber (5) between their facing flat sides (29, 49) in which there is a gas to be pumped, according to the invention the electrodes (2, 4) contain several sections (22, 24, 26 or 42, 44, 46) which are spatially separated from another at least over a part of their thickness (d). Here the electrodes (2, 4) are fitted in such a way that the movement of their flat sides (28, 48) away from the discharge chamber (5) caused by heat expansion is opposed by only a negligible mechanical resistance. This measure means that, even with large electrode areas, any distortion of the resonator caused by bending moments acting on the electrodes and caused by the effect of heat is reduced.

摘要： In order to achieve higher powers in electrically excited gas lasers, the invention calls for the laser to have a discharge space (11) which is formed by two cylindrical electrodes (2, 3), disposed coaxially with respect to each other, and by two resonator mirrors (12, 13) designed so that, in the unstable mode, the laser beam is displaced transversely at each reflection until it emerges at the edge of one (13) of the mirrors which extends over only part of the discharge chamber (11).
