ている。The operation of the conventional axial flow type gas laser oscillator configured as described above will be described below. First cylindrical excitation section (1) in the opening (8a), (8b), CO 2 from (8c), N 2, He
Introducing a laser medium gas containing
Outflow from a) and (9b). In this case, the laser medium gas is circulated in the cylindrical shape excitation part (1) in the axial direction of the cylinder at a speed of about 200 m / sec. Anodes (10a) (10b), (10c) and cathodes (11a), which are provided at the gas introduction part and the gas discharge part,
A high voltage of about 20 KV is applied between (11b) by the DC power supply (12). In this state, the cylindrical excitation part (1)
The laser gas, whose gas pressure was kept at about 70 Torr, was discharge-excited by glow discharge. Mirrors (14a), (14) arranged on the central extension of the cylindrical central axis (4) of the cylindrical excitation part (1) for photons with a wavelength of 10.6 μm emitted from the excited CO 2 molecule.
Mirror (14a) that is a partially transmissive mirror that is resonantly amplified by b).
CO 2 laser light is output from the side. By the way, in order to guarantee the coaxiality of a plurality of cylindrical excitation parts (1), the cylindrical excitation part (1) is supported via the block (2) by the common support (3). In addition, resonator mirrors (14a), (1) are provided on both ends of the common support (3) via base plates (13).
By attaching 4b), the resonator mirrors (14a), (14a)
It ensures the retention of the vertical angle of b) to the cylinder center axis (4). By the way, the stable oscillation operation of the laser is less likely to cause a deviation in the coaxiality of the plurality of cylindrical pump portions (1) and a deviation in the angles of the resonator mirrors (14a) and (14b) with respect to the cylindrical center axis (4). Most important. For this reason, the common support (3) has a structure that minimizes deformation and thermal deformation due to external force, and the material of the common support (3) is an alloy called Invar which has a linear expansion coefficient of about 1/10 of iron. Is used, or the cooling water is controlled to flow within ± 0.5 ° C inside the common support (3). Further, the common support body (3) is a roller (20) or a linear motion guide so that the deformation of the box body (18) does not affect the common support body (3) with respect to the laser oscillator box body (18). The common support (3) is joined to the box (18) by (21). Laser oscillators are often used for metal processing (cutting, welding, surface treatment), but mounting to the processing equipment is done by mounting brackets (22) provided on the box (18). .

いという問題があつた。According to the conventional axial flow type gas laser oscillator configured as described above, the cylindrical central axis (4) of the cylindrical excitation part (1), that is, the laser output optical axis is the fourth with respect to the box (18) of the laser oscillator. As shown in the figure, there is a defect that the optical axis position is not guaranteed and the optical axis position changes due to the deformation of the box (18). Therefore, there is a problem in that it is necessary to adjust the mounting position on the processing device for each oscillator manufactured and to periodically correct or adjust the deviation of the optical axis position that changes with time.
本発明は上記のような問題点を解決するためになされた

It is attached based on. Therefore, the positions of the cylindrical central axes (4) of the plurality of cylindrical excitation parts (1) are guaranteed to be geometrically set by the a and b dimensions with respect to the reference planes (5a) and (5b). On the other hand, the invar (24) indirectly supporting the resonator mirrors (14a) and (14b) also includes the reference plane (5) of the common support (3).

In other words, oscillator reference planes (5a), (5b)
However, the movement direction of the optical transmission system path of the processing device (7) or the workpiece may be set with reference to the central axis (4) of the cylinder that is uniquely determined. As a practical matter, as shown in FIG. 3, the mirror (14a) has a wetting angle θ 0, which causes a deflection angle of θ 1 = (n−1) θ 0 with respect to the cylinder central axis (4). , CO 2 laser, n (refractive index) ≒ 2.4 (ZnSe, 10.
6 μm), θ 0 ≈ 3 ′, θ 1 ≈ 1.2 mRad, which is very small, so there is no problem. When θ 0 is known in advance, it is possible to correct the axis by inserting a spacer or the like on the reference surface.
