摘要： The gas laser oscillator of the invention comprises a discharge tube, a pair of electrodes disposed at both ends thereof, a direct-current high voltage power source for applying a direct-current high voltage in pulse form to the pair of electrodes, an output control device for controlling the direct-current high voltage power source, a fully reflective mirror provided at one end of the outside of the pair of electrodes, a partially reflective mirror disposed at other end of the outside of the pair of electrodes, and an absorber disposed outside of the partially reflective mirror. In thus constituted gag laser oscillator, the output control device controls to apply a same direct-current voltage as during processing between the pair of electrodes also on standby while the absorber is closed. The gas laser oscillator of the invention further comprises a beam splitter outside of the absorber, a switch to be actuated while the beam splitter is installed at a specified position, a focusing lens disposed on the optical axis of the laser beam reflected and separated by the beam splitter, a shielding plate disposed so as to open or close the passage of laser beam, a switch to be actuated while the shielding plate is open, a detector for detecting the laser beam, an amplifier for amplifying the output of the detector, and a medium passage disposed in contact with the detector for realizing heat exchange between the temperature-controlled medium and the detector, whereby it is controlled to issue the laser beam only while the beam splitter is installed at a specified position. The output of the laser beam is controlled so that the detector input may not exceed the maximum allowable input of the detector while the shielding plate is open. Moreover, the beam splitter, focusing lens, and detector are arranged so that the optical axis may be horizontal to the laser beam passing therethrough.

摘要： The gas laser oscillator apparatus of the present invention has a temperature-detecting mechanism disposed at the bearings of the bellows section. The temperature-detecting mechanism detects temperature rise in the bearings and calculates a maintenance cycle with reference to the predetermined data on relationship between temperature and the lifetime of the bearings. Disposed at the bearings, the temperature-detecting mechanism outputs a signal that indicates a replacement cycle according to the temperature of the bearings. More preferable, the temperature-detecting mechanism has a sensor at a tip end of a spring having a pressure force smaller than a load applied to the bearings in advance. To enhance accuracy of temperature detection, the spring is wrapped around with heat insulating material so as not to be exposed to outside temperature.

The gas laser oscillator according to the present invention includes a laser gas flow pipe, a driving part, a divide wall, a main ejection apparatus, a sub ejection apparatus, a detect portion, and a clogged laying pipe judge part. The laser gas flow pipe constitutes a circulating route of the laser gas. The driving part drives the air blower for blowing the laser gas. The divide wall separates the air blower and the driving part. The main ejection apparatus has a valve, and ejects laser gas from the laser gas flow pipe. The sub ejection apparatus ejects laser gas from the driving part. The detector detects an amount of laser gas ejected from the main ejection apparatus and the sub ejection apparatus. The clogged laying pipe judge part judges that the laying pipe of the sub ejection apparatus is clogged when an amount of ejected laser gas measured at a time the valve of the main ejection apparatus is closed is lower than a predetermined value.
