Abstract
The utility model relates to a laser device, and especially relates to a cooling device for a laser reflection mirror. The cooling device comprises a cooling jacket and a heat-conducting sheet disposed on the cooling jacket. During installation, the heat-conducting sheet is attached tightly to the laser reflection mirror, so as to enable the heat on the laser reflection mirror to be conducted to the heat-conducting sheet and enable the cooling jacket to cool the heat-conducting sheet, thereby achieving the purpose of cooling the laser reflection mirror. Because the heat-conducting sheet is disposed between the cooling jacket and the laser reflection mirror, the cooling jacket is stopped from directly contacting with the laser reflection mirror and cooling the laser reflection mirror, thereby reducing the temperature difference between the cooling jacket and the laser reflection mirror, reducing a temperature gradient of the laser reflection mirror, improving service precision of the laser reflection mirror, and prolonging the service life of the laser reflection mirror.
Description
Technical field
The utility model relates to a kind of laser device, particularly a kind of laser mirror sheet cooling device.
Background technology
In current laser, discharge tube is normally made by glass or quartz material, and the inside is filled with carbon dioxide and other assist gass; Electrode is generally nickel hollow cylinder processed; One end of resonant cavity is reflecting optics, and the other end is the output eyeglass.When add high voltage on electrode, produce glow discharge in discharge tube, form laser beam after mirror-reflection.Laser has larger power and higher energy conversion efficiency, and spectral line is also abundanter, and the Laser output of tens spectral lines is arranged near 10 microns, at aspects such as industry, military affairs, medical treatment, scientific researches, is widely used.
Current laser only has portion of energy to be converted when laser occurs in using, the heat energy that all the other power conversion are gas, elevate the temperature, and the rising of gas temperature, to cause that disappearing of upper laser level excites the thermal excitation with laser lower level, this all can make the inverted population of particle reduce; And the rising of gas temperature, will make broadening of spectral lines, cause gain coefficient to descend; Particularly, the rising of gas temperature, also will cause the decomposition of carbon dioxide molecule, reduce the carbon dioxide molecule concentration in discharge tube, and these factors all can make the power output of laser descend, and even produce " temperature quenching ".
At present in order to reduce the temperature of laser, it is the temperature that sheathed cooling device reduces discharge tube outside discharge tube, reflecting optics at the laser two ends arranges respectively the cooling reflecting optics of cooling device and the temperature of exporting eyeglass with exporting on eyeglass, the cooling device used at present, inside has cooling fluid storage to receive chamber, and is provided with cooling liquid inlet and cooling liquid outlet on chamber is received in the cooling fluid storage.In use, cooling device is adjacent to output eyeglass and reflecting optics, and cooling fluid enters the cooling fluid storage from cooling liquid inlet and receives chamber then from the cooling liquid outlet outflow, thereby realizes cooling output eyeglass and reflecting optics purpose.
In actual the use, for reflecting optics, only have the reflecting optics of mid portion to be reflected laser beam, laser beam does not drop on the eyeglass of periphery, thereby has caused the temperature on the reflecting optics to present from middle part the temperature gradient progressively reduced to the periphery.
Current laser mirror sheet cooling device is that integral plaster is combined on reflecting optics, reflecting optics is carried out to the cooling of integral body, although the temperature of reflecting optics has obtained reduction, but on reflecting optics still present the middle part temperature relatively high, and the relatively low temperature gradient of peripheral temperature, this temperature gradient appears on reflecting optics, make the expansion amplitude at reflecting optics middle part be greater than peripheral expansion amplitude, also reduced the working life of reflecting optics when affecting the reflecting optics service precision.
