摘要： A gas laser oscillating unit having a gas junction part (23) 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 (3a,3b), is introduced into the first and second tapered gas flow passages (61a,61b). After that, the two gas flows (80a,80b) are mixed at or near the center point (51) of a gas junction part (23) and the mixed gas flows in a next flow passage (62). Then, one of the gas flows from the first excitation part is biased toward the -X direction by a first biasing member (70a) 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 (70b) arranged in the second gas flow passage. The first gas flow passage (60a,61a) from the first excitation part (3a) to the gas junction part (23) and the second gas flow passage (60b,61b) from the second excitation part (3b) to the gas junction part (23) may be 180-degree rotationally-symmetric about a center axis (52) extending through the center point (51) of the gas junction part (23) and perpendicular to the laser axis (4).

摘要： A laser unit having a preparatory function for activating the unit and an activation method for the unit, capable of stabilizing the temperature of each component of the laser unit in the preparation stage when the laser unit is activated in a low-temperature or high-temperature environment, and then effectively judging completion of the preparation. During a period of time Ta from T1 to T2, a first trial of laser oscillation is performed. After a period of time Tb in which the laser is not oscillated, a second trial of laser oscillation from T3 to T4. Such an operation is repeated until a predetermined criterion is satisfied. 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 apparatus including a laser oscillating section (12), electric power source (14), a laser-power measuring section (16) and a power-source controlling section (18). The power-source controlling section (18) includes a power-supply instructing section (20) instructing the power source to perform an electric-power supplying operation for the laser oscillating section in response to a laser-oscillation command value; and a function calculating section (22) determining, based on different laser-oscillation command values given to the power-supply instructing section and different laser-power measured values obtained by the laser-power measuring section, a function approximatively representing a correlation of the laser-power measured values relative to the laser-oscillation command values. The power-supply instructing section executes, after the function is determined, a correcting process for a laser-oscillation command value based on the function, and instructs the electric power source to perform the electric-power supplying operation in response to the corrected laser-oscillation command value.
