Abstract

PURPOSE:To remove the influence of a thermal strain on a laser tube thereby to reduce the variation in an optical axis of a laser by movably supporting the two points of a lower invar rotatably at one point in a linear direction, and suspending a laser tube movably from the upper invar. CONSTITUTION:Invars 31-34 are clamped by nuts 35-38 to flanges 21, 22 on a base 1, lower invars 33, 34 are held by supporting members 45, 46 through rod materials 43, 44 by members 41, 42, and the materials 43, 44 are rotatable with respect to the members 41, 42 and 45, 46. Further, the invars 33, 34 are coupled to the members 51, 52, and supported at a position C by a holder 54 through a rod material 53. Laser tubes 61, 62 are flexibly coupled to the flanges 21, 22, suspended by suspending members 63, 64 from the invars 31, 32, and the tubes 61, 62 are made laterally movable. Thus, even if the tubes 61, 62 are elongated or Shrunk due to temperature change, they are not applied with a strain in lateral directions.
