Abstract
PURPOSE:To realize the long life of a laser tube by a method wherein a blower is provided between the cathode and the cathode side optical window of the outer tube of the laser tube and blows air against rare gas containing melted particles which flows from the through-hole of the cathode toward the cathode side optical window to change the flow route of the rare gas to the direction crossing the center axis of the thin tube of the laser tube and the cathode side optical window is protected from adhesion of the melted particles. CONSTITUTION:A blower 9 is provided between the inside cathode 3 and the cathode side optical window 5a of an outer tube 6. The blower 9 blows air along the direction perpendicular to the center axis of a thin tube 1 against rare gas flowing from the through-hole 3a of the cathode 3 toward the cathode side optical window 5a to change the flow route of the rare gas toward the direction shown by arrows 10. As a result, the flow of the rare gas containing melted particles runs against the wall of the outer tube 6 away from the cathode side optical window 5a and makes the particles adhere to the wall. Therefore, the cathode side optical window 5a is protected from the adhesion of the melted particles.
