Abstract: A support unit (20a) for supporting an OPM holder (15a) so as to be vertical to the laser beam axis is disposed in the lower part of the OPM holder (15a). A rotary shaft (19) is inserted into the support unit (20a) and rotary shaft support unit (20b), and the OPM holder (15a) and DT base (17) are assembled together. Thus, a rotation support unit (200) is composed. The rotation support unit has a degree of freedom in the rotating direction of arrow (202). On the other hand, in the lower part of an RM holder (15b), a support bar (21) is provided. At the DT base (17), a rotating element (22) and a rotating element support unit (23) supporting the rotating element are composed so as to support the support bar. Thus, a slider structure (220) slidable in the optical axis direction is formed. The slider structure has a degree of freedom in the direction of arrow (222).

Abstract: 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.

Abstract: 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.
