Embodiment Construction

[0029] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following drawings, the same reference symbols are attached to the same members. For easy understanding, these drawings are appropriately changed in reduced scale.

[0030] First, a laser oscillator having a blower according to the present invention will be described with reference to FIG. 2 . In FIG. 2 , as an example of a laser oscillator to which the present invention is applied, there is shown a relatively high-output gas laser oscillator of the induction discharge excitation type, such as a carbon dioxide laser oscillator 100 . The laser oscillator 100 is provided with: a discharge tube 102; and a suction line 104a for a laser medium that sucks in gas from an approximately central portion in the longitudinal direction of the discharge tube 102, and discharges the laser medium to portions adjacent to both ends of the discharge tube 102. The circulation path 1...

Abstract

A blower ( 10 ) includes: at least two or at least three acoustic sensors or vibration sensors ( 31 a to 31 c) attached to a casing ( 12 ); and a position specifying means ( 34 ) for specifying a position of a source of abnormal sound or abnormal vibration from signals detected by the acoustic sensors or vibration sensors. When the position of the abnormal portion is specified in this way, a proper countermeasure can be taken quickly. Further, the blower ( 10 ) preferably includes an alarm output judging means ( 35 ) for judging whether or not an alarm should be outputted according to the position of the source of the abnormal sound or abnormal vibration specified by the position specifying means. A laser oscillator ( 100 ) having the blower ( 10 ) is also provided.

Description

technical field [0001] The present invention relates to a blower for a laser oscillator. In particular, the present invention relates to a blower for a laser oscillator used in a laser oscillator using a gas as a laser medium, such as a chemical laser or a gas laser, to circulate the laser medium. Furthermore, the present invention relates to a laser oscillator having such a blower. Background technique [0002] In recent years, laser oscillators have been used in the fields of laser processing, medical treatment, lighting or communication. Such laser oscillators include gas laser oscillators using gas as a laser medium, such as chemical lasers and gas lasers. In the gas laser oscillator, the laser medium, such as carbon dioxide, is circulated between the discharge tube and the heat exchanger, and the carbon dioxide is maintained at an appropriate temperature. [0003] Fig. 4a is an axial sectional view of a centrifugal blower used in a conventional laser oscillator. Fig...
