The utility model discloses an at the built -in multiple -unit tube window lens of tub window box body to through the removal of portable tub of window seat, can make an arbitrary pipe window lens in the pipe window lens is located and pierces through entirely between lens and the light source business turn over hole, and the structure of this kind of multiple -unit tube window lens switching work is convenient for maintain tub cleanliness factor of window lens, and then maintains the energy stabilization and improve the reaction gas rate of utilization.
Description
Technical field
The utility model relates to gas laser field.
Background technology
The schematic diagram of the gas laser shown in Fig. 1, under the effect of driving source (high-voltage power supply 2), there is gas concussion, produce diverging light in the gas between two battery lead plates 1; In order to ensure that gas shakes, preventing energy to run off too fast, being respectively arranged with laser tube form 3 and speculum 4 at the two ends of battery lead plate, shake by gas the light produced and get back to zone line after laser tube form, speculum.
In practical work process, the gas laser in gas laser is after continuous agitation a period of time, and energy can slowly fail, and driving source also can raise because of the output that will maintain certain energy, and then overall laser stability is deteriorated.
The reason that energy can be caused to fail is a lot, and such as: anodizing or damage, gas circulation is deteriorated, all factors such as cryogenic pump performance degradation.If eliminating external factor, the reason of energy fall off is broadly divided into two classes:
1, pipe visual window lens is dirty;
2, mist is aging.
When reaching certain laser pulse number, needing to perform laser gas and to change and pipe visual window lens cleans, and when each ventilation operation, all find that pipe visual window lens makes because gas laser impacts the dirty and laser labelling in surface remain.
The index judging more replace tubes visual window lens (tubewindow) and change laser tube reaction gases is ELAconditioninspection (judgement of energy rank), detect " bright band " (the perfect crystal region of Poly-Si) and whether have enough energy widths to meet demand, if pipe visual window lens surface has dirty, excitation source hindered when then can be made to penetrate, and then cause laser energy to decay, high-voltage power supply (Hv) raises, bad stability, energy width reduces thereupon, therefore exist " mist is aging " front have to perform change laser tube reaction gases or more replace tubes visual window lens.Pipe visual window lens cleanliness requirements and driving source increase and the situation of rising with step-by-step counting as seen from Figure 2.Can be drawn by this figure:
1, Hv(high-voltage power supply) with laserpulse(step-by-step counting) increase and raise;
2, Hv(high-voltage power supply) fiducial value with pipe visual window lens access times increase and improve;
3, the factor weight of LaserGaslife utilization rate is affected: pipe visual window lens dirty > mist is aging.
If so when LASER Light Source passes through pipe visual window lens, without dirty impact, the utilization rate of gas and the stability of laser energy should be improved.
