摘要： A laser oscillator includes a blower for blowing laser gas to discharge tubes; a gas circulation path for connecting discharge tubes and a blower; a gear chamber pressure detector for detecting the pressure of the gear chamber disposed in the blower; and an alarm part for issuing an alarm when the pressure detected in the gear chamber pressure detector is higher than a predetermined pressure. The predetermined pressure is set based on the average value of the pressure on the laser gas inlet side and the pressure on the laser gas outlet side of the blower. This configuration can prevent the entry of the oil mist generated from the blower into the gas circulation path and an increase in the gas consumption, while maintaining stable laser output for an extended period of time without increasing the running cost.

摘要： A gas laser oscillator comprising a laser gas pressure controller for controlling the pressure of laser gas in laser gas chamber to be constant, an electromagnetic valve for supplying laser gas into the laser gas chamber from a gas bottle so that the laser gas within the laser gas chamber is maintained constant, detection means for detecting that the cycle period of open/close actions of the electromagnetic valve became longer than a reference value, and an alarm display controller which issues an alarm. In a gas laser oscillator of the present invention, even such a micro vacuum leak that hardly ill-affects the laser output can be detected with ease while the gas laser oscillator is in operation. This makes it possible to apply an appropriate maintenance work beforehand on the vacuum seal. Thus, reliable gas laser oscillators can be offered in accordance with the present invention.

摘要： The present invention relates to a laser generator in which a laser beam is generated by energizing a laser medium and is amplified optically with optically amplifying mirrors, and the laser beam is received by a absorber, wherein a spacer 9 having a through hole 9a for passing therethrough the laser beam and at least one small second through hole 9b is arranged at a circumference of an absorber 7, and a cooling medium 12 circulates in the small second through hole 9b of the spacer 9. In this structure, if a scattering laser beam is generated at the circumference of the laser beam absorber, a parallelism of the optical amplifying mirrors is maintained so that the laser generator can generate the stable laser beam.
