Abstract
The invention relates to a laser device, in particular to a reflecting window for a carbon dioxide laser. The reflecting window comprises a cooling device, a reflecting lens is arranged on the cooling device, an installation frame is further arranged on the cooling device, a lens installation hole is formed in the installation frame, one end of the installation frame is arranged on the cooling device, a stop block is arranged at the other end of the installation frame, the reflection lens is arranged in the lens installation hole of the installation frame, and a spring is arranged between the reflecting lens and the stop block. When the laser works, due to the fact that the reflecting lens is tightly pressed on the cooling device through the spring, even if the thermal expansion coefficients of the cooling device, the reflecting lens or the installation frame are different, the reflecting lens still can be tightly pressed by the spring to be attached to the cooling device after being heated, so that the situation that laser rays output by the carbon dioxide laser are influenced due to the fact that the thermal expansion coefficients of the reflecting lens and the cooling device are different is avoided.
Description
Technical field
The present invention relates to a kind of laser device, particularly a kind of reflection window of carbon dioxide laser.
Background technology
Current carbon dioxide laser, generally include discharge tube, be set in the cylinder of discharge tube outside, output window and the reflection window that is arranged on negative electrode and the positive electrode in discharge tube and is arranged on two ends, the reflection window includes reflecting optics and reflecting optics cooling device, output window includes output eyeglass and output eyeglass cooling device, in discharge tube, fills with carbon dioxide and other assist gass; When on negative electrode and positive electrode, adding high voltage, in discharge tube, produce glow discharge, after reflecting optics and output lens reflecting, form laser beam, laser beam is from penetrating the output eyeglass.Because carbon dioxide laser has larger power and higher energy conversion efficiency, spectral line is also abundanter, and the Laser output of tens spectral lines is arranged near 10 microns, all is widely used at aspects such as industry, military affairs, medical treatment, scientific researches.
The reflection window of current carbon dioxide laser, reflecting optics is fitted on cooling device by bonding agent, reflecting optics is carried out to the cooling of integral body, although the temperature of reflecting optics has obtained reduction, but due to reflecting optics and cooling device material used different, so the thermal coefficient of expansion of reflecting optics and cooling device is inconsistent when being heated, after the laser Reusability, between cooling device and reflecting optics, be prone to crack, not only affected the cooling effect of cooling device to reflecting optics, also make the alignment accuracy of reflecting optics and output eyeglass reduce, and directly affect the quality of carbon dioxide laser Output of laser.
And, in the reflection window of current carbon dioxide, for reflecting optics can firmly be arranged on cooling device, so the blind hole matched with reflecting optics is set on cooling device corresponding to reflecting optics, reflecting optics is arranged in blind hole, then brushing bonding agent between the bottom surface of reflecting optics and blind hole, although adopt this structure firm being connected between reflecting optics and cooling device, but in current processing technology, because the grinding machine attrition process can not be passed through in the bottom surface of blind hole, so the flatness precision of blind hole bottom surface is not high, reflecting optics can not be good with the blind hole bottom surface laminating, thereby it is good cooling to have caused cooling device not carry out reflecting optics, and, because the flatness precision of blind hole bottom surface is low, thereby caused the installation accuracy of reflecting optics low, directly affected the quality of laser Output of laser, in addition, owing to being provided with blind hole, fitted in the bottom surface of reflecting optics and blind hole, so, the depth of parallelism between the end face of the bottom surface of blind hole and cooling device installation end has also determined the installation accuracy of reflecting optics, also because the blind hole bottom surface is difficult to carry out accurate processing under existing processing technology, so after blind hole processes on cooling device, the bottom surface Pingdu precision that is on the one hand blind hole is not high, that blind hole bottom surface and cooling device installation end faces parallel precision are not high on the other hand, based on these factors, make the reflecting optics installation accuracy not high, be that output eyeglass alignment accuracy in reflecting optics and laser is low, directly reduced the output quality of laser in the laser.
So needing at present a kind of can either avoiding badly affects the output quality of carbon dioxide laser laser due to reflecting optics and cooling device because thermal coefficient of expansion is inconsistent, can improve again the reflection window construction of the carbon dioxide laser of reflecting optics installation accuracy.
Summary of the invention
The object of the invention is to: in existing laser, due to reflecting optics and the cooling device thermal coefficient of expansion inconsistent, and cause the affected deficiency of carbon dioxide laser Output of laser, provide a kind of can avoid because of reflecting optics and the cooling device thermal coefficient of expansion inconsistent, and cause the reflection window construction of the affected carbon dioxide laser of carbon dioxide laser Output of laser.
To achieve these goals, the technical solution used in the present invention is:
A kind of reflection window of carbon dioxide laser, comprise cooling device, on described cooling device, be provided with reflecting optics, on described cooling device, also be provided with installing rack, on described installing rack, be provided with the eyeglass installing hole, an end of described installing rack is connected with described cooling device, and the other end of described installing rack is provided with block, described reflecting optics is arranged in the eyeglass installing hole of described installing rack, is provided with spring between described reflecting optics and described block.Installing rack is arranged on cooling device, and reflecting optics is arranged on to installing rack inside, by spring, reflecting optics is pressed on cooling device, eliminates the end play between reflecting optics and cooling device.The laminating that reflecting optics and cooling device are good, when laser works, due to reflecting optics by spring compression on cooling device, so, even the thermal coefficient of expansion of cooling device, reflecting optics or installing rack is inconsistent, after being heated, reflecting optics still can be adjacent on cooling device by spring compression, thereby avoided because of reflecting optics and the cooling device thermal coefficient of expansion inconsistent, and cause the affected situation of carbon dioxide laser Output of laser, in addition, because reflecting optics is arranged on cooling device by installing rack, thereby need on cooling device, not offer the blind hole of placing reflecting optics, the end face of cooling device is the mating surface of cooling device and reflecting optics, end face is set to mating surface like this, adding man-hour, can directly with grinding machine, process the mating surface of cooling device, make the flatness of mating surface have higher precision, so reflecting optics can be fitted closely with cooling device, so not only improved the cooling effect of cooling device to reflecting optics, and improved the installation accuracy of reflecting optics, and then improved the positive alignment accuracy of reflecting optics and output eyeglass, improved the quality of laser Output of laser.
As preferred version of the present invention, the hollow cylindrical shell connected centered by described installing rack.Installing rack is set to the hollow cylindrical shell of through, has reduced the weight of whole reflection window, also makes installing rack simple in structure, convenient processing.
