    摘要: The present invention can accurately detect a wavelength of a light to be detected, which is output from a source of light to be detected, without an error even if there is a change in the characteristic of a spectroscope due to an individual difference among the spectroscopes or a change in the measuring environment. The device according to the invention emits at least two reference lights (Ln, La) having different wavelengths (&lgr;n, &lgr;a) as the reference lights by reference light source. And, actual characteristic value (D) of spectroscope is calculated on the basis of detection positions (Sn, Sa) of the at least two reference lights (Ln, La) on a sensor and the known wavelengths (&lgr;n, &lgr;a) of the at least two reference lights (Ln, La) (D=(&lgr;a−&lgr;n)/(Sa−Sn)). And, on the basis of the detection positions (Sn, SO) of the reference light (Ln) and the light to be detected (LO) on the sensor (10), the calculated actual characteristic value (D) of the spectroscope and the known wavelength (&lgr;n) of the reference light (Ln), wavelength (&lgr;O) of the light to be detected (LO) is calculated (&lgr;O=&lgr;n+(SO−Sn)·D).

    摘要: A buffer gas contained in a laser gas used for an ArF excimer laser mainly consists of He, and Xe is preferably added to the laser gas. Mixture piping divided by valves is disposed on piping running from a chamber to an excimer laser gas cylinder, the mixture piping and a Xe gas cylinder are connected, gas exhaust by a gas exhaust module and opening and closing of the valves are controlled by a gas controller to add a trace quantity of xenon gas to the excimer laser gas. Thus, to remedy a burst characteristic and a spike characteristic of the ultraviolet laser device by adding a trace quantity of xenon gas, the xenon gas can be supplied efficiently into the chamber without modifying existing laser gas supply equipment.

    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.
