本発明は、レーず共振器を空冷する空冷型レーザ発振器

ず発振器では空冷させ 。Conventionally, this type of air-cooled laser oscillator has placed a fan around the laser resonator that generates high heat, and has holes around it for intake and exhaust, holes for the laser tip exit, holes for adjusting the mirror angle, etc. It was covered with an open case. However, conventional laser beam oscillators require air cooling.

らなくなるという欠点がちり九。When ambient air is taken in by a fan, it is naturally taken in from the laser light exit hole in addition to the intake hole.・Although the ambient air differs depending on the usage environment, it contains a certain amount of dust, and when it is taken in, it is drawn in through the laser beam exit hole. When the mirror comes close to the hole and faces on the same line, it collides with the laser output side mirror □, and then it hits the wall K of the mirror holding plate for adjusting the mirror angle.
fB flows in four directions. For this reason, some of the dust contained in the surrounding air and flowing into the laser oscillator was likely to adhere and accumulate on the surface of the laser output mirror. As a result, in conventional air-cooled laser laser oscillators of this type, the laser output decreases after several tens of hours due to dust, depending on the usage environment.For this reason, it is necessary to clean the laser output mirror surface. I had to. Also, if this happens repeatedly, this dust (due to the laser beam) will be burned onto the mirror surface and cannot be removed even with cleaning, resulting in the need to replace the mirror.

低下やミラーの劣化という従来の欠点が改善される。In the present invention, the laser beam path is suspended in the space between the inside of the front panel of the oscillator case where the laser beam exit hole of the air-cooled laser □ oscillator is located and the mirror holding plate for adjusting the mirror angle on the laser output side. In addition, the material that is inserted tightly into the walls of both the panel and the holding plate, and which is very light and has sufficient elasticity, is made of sand, and the part corresponding to the light path is made of plastic. Since it is equipped with a dust-proof intake air shield tube, there will be no leakage when air is taken in by the air cooling fan.

This prevents air intake through the laser output port hole, suppresses the inflow of this dirt, and also suppresses the adhesion of dirt to the surface of the cutter. The conventional drawback of deterioration is improved.

The argon ion laser oscillator 1 has a laser resonator 20 that generates high heat, and a laser resonator 20 that generates high heat.

される。 ”゛Although the surrounding air 11 differs depending on the usage environment, it contains a certain amount of dust →1. ．． 1- Hole 7 for laser light exit during intake
After the surrounding air 11 is sucked in from the hole 7, it comes close to the hole 7 and collides with the laser output side mirror 8, which is opposite to the mirror on the same line. It flows in all directions at 8-) on the wall surface of the angle adjustment mirror holding plate 12. For this reason - ambient air 11
A part of the dust that was included in the laser beam and flowed into the inside of the laser oscillator 1 tended to adhere to and accumulate on one surface of the laser output mirror 8. As a result, the conventional air-cooled argon ion laser oscillator 1 has the disadvantage that the laser output decreases during use and the laser 8 deteriorates due to this kind of dust.゛゛Figure 2 shows an embodiment of the present invention. The present invention is applied to the inside of the front panel 14 of the case 10 of the oscillator 13 in which the laser beam exit hole 7 of the air-cooled argon ion laser oscillator 13 is located, and the electric tool holding plate 12 for adjusting the mirror angle of 5 degrees on the laser output side. so as to enclose the laser optical path 6 in the space 15 between the
In addition, it is inserted in close contact with the walls of both the panel 14 and the holding plate 12, and is very light and elastic so as not to put pressure on the mirror angle adjustment mirror holding plate 1 and 2 and distort the optical axis 6. 3. Material with sufficient properties such as sponge or structure. For example, an accordion-type one is made, and the part 16 corresponding to the laser beam path 6 is rounded and equipped with an air intake shielding tube 17 for dustproofing, which is a laser output port when air is taken in by the air cooling fan 3. The intake passage from the air hole 7 is connected to the shell shielding tube 17.
Since the air is blocked by the laser output hole 7, air intake from the laser output hole 7 is blocked, and the inflow of dust and furthermore the adhesion of dust 1(t) to the surface of the cutter is also suppressed.
``From the above, the present invention can eliminate the use of conventional air-cooled argon ion laser oscillators.
This improves the deterioration of the laser output due to dirt inside. ”゛
