IPC: H01S3/0977
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a laser device with which a stabilized laser can be oscillated when the laser device is operated at a high repeated oscillation frequency without requiring a large fan to be used to enhance the velocity of back flow gas. SOLUTION: An upstream spare ionized electrode 2a is arranged separately in the distance d1 from the main electrode 1b in a chamber 10, and a downstream spare ionized electrode 2b is arranged separately in distance d2 (d2>d1) from the main electrode 1b. Even when the intensity of the discharge of both spare electrodes 2a and 2b is equal, as the downstream spare ionized electrode 2b is arranged on the further side by the main electrode 1b than the upstream spare ionized electrode, the strength of the spare ionized electrode affecting the main discharge region increases on the upstream side and decreases on the downstream side. Next main discharge operation can be performed in the state wherein the introduction of dust on the downstream is suppressed, and the distortion of cross secion of the laser beam can be suppressed.
