PROBLEM TO BE SOLVED: To obtain a laser oscillating device, wherein workability for cleaning of a window and the like is good and a gas leakage is hardly generated after the widow is mounted on a slide cassette. SOLUTION: A rorary driving rod 15 is inserted in an insertion hole 12a provided in a push ring 12 and the ring 12 is rotated conunterlockwise toward a container 2. Consequently, the ring 12 is moved to the side of a resonance mirror 3, a fixing of a window 5, which has been pressed to the side of the container 2 by a press ring 11, is removed from the container 2, and the window 5 can be pulled outside a window housing 33 along with a slide cassette 10. Then the window 5 is taken out from the pulled-out slide cassette 10 to clean the window 5. A fixing of the window 5 subsequent to the cleaning is performed in a process reverse to the above process. |
