摘要： PURPOSE:To reduce the adhesion of an impurity to a mirror and the like at the time of replacing the mirror and to increase the life of medium gas by incorporating a mirror section detachably controlled to a laser tube in a mirror replacing box isolated from the external atmosphere. CONSTITUTION:A mirror replacing box 10 isolated from the external atmosphere is provided, and a mirror 14 is contained in the box. The mirror 14 is pressed to a laser tube 1 at the time of laser oscillation. The connection of the mirror 14 employed at present to the tube 1 is released at the time of replacing the mirror, and the mirror 14 is replaced with a new mirror to be replaced. In this case, the interior of the box 10 is isolated from the outer atmosphere, and since the replacement is conducted in the box 10, the adhesion of an impurity to the new replaced mirror in a mirror section can be remarkably reduced.

摘要： PURPOSE:To enable lubricant to be injection-supplied at any time without deteriorating the airtightness by a method wherein the lubricant is enabled to be injected into a bearing inside a laser tube through a lubricant hole from a dispenser outside the laser tube by opening and closing a gas sealing means. CONSTITUTION:A gas sealing valve 30 is closed to vacuumize a laser tube; the laser tube is baked before filling it with laser buffer gas up to the atmospheric pressure ; next the gas sealing valve 30 is opened from a dispenser 29; and proper amount of lubricant is injected into a bearing 27 through an oil hole 28 of flanges 25 and 26. After injecting the proper amount, the gas sealing valve 30 is closed further to fill the laser gas. Through these procedures, the lubricant can be injected after previously baking the laser tube so that the lubricant may be supplied without unsealing the laser tube after long time operation.

摘要： PURPOSE:To reduce absorption loss of X-rays by a method wherein the covering material of an incident window is made of a thin film as thin as possible to seal hermetically laser medium gas, and a protective frame constructed by arranging the plural number of small incident windows is adhered closely thereto. CONSTITUTION:An X-ray incident window 5 is formed at one side part of a laser tube 3 facing to discharge electrodes 2a, 2b, and a flange 9 is formed at the outside periphery of the incident window 5. A thin film 11 is set in a hermetical condition to the flange 9 interposing a seal material 10 between them, a protective frame 13 consisting of the aggregate of small incident windows having honeycomb structure is adhered closely to the thin film 11 moreover interposing a seal material 12 between them, and a supporting frame 14 is pressed thereto to be fixed. As the protective frame 13, Al foil of 20-40#,mm thickness is used, for example. Although the film 17 of the protective frame 13 and the thin film 11 are closely adhered to be fixed, when a gap is generated at the center part, and air is contained therein, because there is the possibility of damage of the thin film 11 when the inside of the laser tube 3 is evacuated, the gap is evacuated and after then a tube for regulation of atmospheric pressure 18 is blockaded.
