摘要： A film is formed on the discharge parts of the main discharge electrodes. In order to prevent erosion of the discharge parts by the halogen gas contained in the laser gas, a substance that tends not to react with the halogen gas, i.e., a halogen-resistant substance, is used for this film. Furthermore, in order to prevent deformation of the discharge parts by the bombardment and heat of the main discharge, a substance that has a higher hardness than the metal of the main discharge electrodes or a substance that has a higher melting point than the metal of the main discharge electrodes is used for this film. As a result, deterioration of the electrodes can be inhibited, so that a stable laser output can be obtained, and the replacement interval of the electrodes can be extended.

摘要： An excimer laser apparatus is provided with a compact high efficiency dust particle removal means which is capable of maintaining the windows clean with only a small volume of purging gas, and which prevents deterioration of aperture masks without having to increase the cavity length or risking the possibility of leakage from piping connections. The excimer laser apparatus uses, as dust particle removal means, filters (13a and 13b) made of metal or ceramic which is non-reactive with fluorine. A ground potential dust collector can be provided at a downstream side of a static dust particle remover, having an anode and a cathode, for collecting any dust particles which have passed through the static dust particle remover. In addition, clean laser medium gas can be introduced into subchambers (14a and 14b) through gas introducing passages (11a and 11b) provided in the walls of the housing (1) and then into the laser chamber (12) through labyrinths (8a and 8b) without disturbing the clean gas which stays near the internal surfaces of the windows (6a and 6b).

摘要： Provided is a gas laser electrode in which a stable laser output can be obtained by inhibiting the deterioration of the electrode (discharge characteristics). In an anode 3, a dielectric material 4 is applied on the surface of a discharging portion 3a in order to inhibit the deterioration of the electrode.

Further, the dielectric material 4 is of a thickness (in a range of 0.005 mm˜1.5 mm, preferably 0.1 mm˜1 mm, for example) sufficient to prevent the erosion of halogen gas in the discharging portion 3a of the anode 3 and to secure a conductivity thereof, whereby it is enabled to form mono-fluoride evenly in extreme precision.

摘要： When a chamber of an oscillator and one or more amplifiers is to be replaced at the timing when a predetermined period elapses, one of the chambers of the oscillator and the amplifiers having a low allowable deterioration limit is detached and this chamber is attached in place of one of the chambers of the oscillator and the amplifiers other than the one having the low allowable deterioration limit. Thus, the chamber which has been used in one of the oscillator and amplifiers having a low allowable deterioration limit and has not reached the limit of deterioration is reused in one of the oscillator and the amplifiers other than the one having the low allowable deterioration limit. This enables efficient use of oscillator and amplifier chambers in a multistage amplification laser apparatus, minimizing the labor and parts consumed for replacement thereof.

摘要： In an excimer laser apparatus in which halogen gas, rare gas and buffer gas are fed into the laser chamber, before laser oscillation, the oscillation stop time is calculated, and, if the calculated oscillation stop time exceeds a prescribed time, the calculated oscillation stop time is used to calculate a feeding amount of mixed gas comprising rare gas or buffer gas, and the mixed gas is fed, prior to laser oscillation, in the calculated feeding amount; stable laser output is thereby obtained from the initial period of laser oscillation.
