摘要： A gas laser oscillating unit having a gas junction part where gas flow may be stable, whereby a stable laser beam output and/or a laser beam that does not fluctuate very much may be achieved. The laser gas, flowing through first and second excitation parts, is introduced into the first and second tapered gas flow passages. After that, the two gas flows are mixed at or near the center point of a gas junction part and the mixed gas flows in a next flow passage. Then, one of the gas flows from the first excitation part is biased toward the −X direction by a first biasing member arranged in the first gas flow passage, and the other gas flow from the second excitation part is biased toward the +X direction by a second biasing member arranged in the second gas flow passage.

Laser output values P2, P4, P6, . . . , at the last moment in each trial of laser oscillation are recorded. Then, each difference between the laser outputs at the last moments of two neighboring or continuous trials, is calculated. When the difference is lower than a predetermined criterion value, the preparation of the laser unit is judged to be completed.

摘要： A laser resonator allows internal optical mirrors to be cleaned easily and minimizes any contamination of the internal optical mirrors. The laser resonator has normally closed cleaning windows disposed immediately in front of output, rear, and folding mirrors for inserting a cleaning instrument therethrough for cleaning these mirrors. A gas inlet discharge tube holder has a discharge tube coupling which interconnects the spaces in parallel discharge tubes for transmitting a laser beam therethrough. The gas inlet discharge tube holder also has a gas flow bypass for bypassing a laser gas that circulates through the discharge tubes. The internal optical mirrors can be cleaned easily with a cleaning instrument inserted through the cleaning windows. As the internal optical mirrors do not need to be removed for cleaning, they and an external optical system are not required to be readjusted for alignment of their optical axes. Any contamination of the internal optical mirrors is minimized because no laser gas flow is caused in the discharge tube coupling.
