Description
Technical field
The utility model relates to carbon dioxide laser device, particularly carbon dioxide laser output coolant jacket.
Background technology
Carbon dioxide laser is the gas laser using carbon dioxide as operation material, and discharge tube is normally made up of 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 output eyeglass.When add high voltage on electrode, in discharge tube, produce glow discharge, after output eyeglass and reflecting optics reflection, form laser beam.Carbon dioxide laser has larger power and higher energy conversion efficiency, and spectral line is also abundanter, has the Laser output of tens spectral lines near 10 microns, is widely used at aspects such as industry, military affairs, medical treatment, scientific researches.
In use, on electrode, apply high voltage, current carbon dioxide laser only has portion of energy to be converted in the time there is laser, all the other power conversion are the heat energy of gas, elevate the temperature, and the rising of gas temperature will cause that disappearing of upper laser level excites and the thermal excitation of 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 decline; Particularly, the rising of gas temperature, also will cause the decomposition of carbon dioxide molecule, reduces the carbon dioxide molecule concentration in discharge tube, and these factors all can make the power output of laser decline, and even produce " temperature quenching ".
, in order to reduce the temperature of laser, is at present the temperature that sheathed cooling water pipe reduces discharge tube discharge tube outside, on the reflecting optics at laser two ends and output eyeglass, the cooling reflecting optics of coolant jacket is set and exports the temperature of eyeglass.
The coolant jacket using is at present generally two kinds of structures, one is with glass or the integrated water collar of metal material, due to this integral type water-cooled cover processing difficulty, the factors such as production efficiency is low, so on market out the water collar of split-type structural, the structure of Split type water-cooling cover is generally and the conducting strip of eyeglass laminating and the cooling sheath body being tightly connected with conducting strip, cooling sheath body is formed cooling fluid storage by conducting strip sealing and receives chamber, although adopt the water collar of split-type structural to solve processing difficulties, the problem that production efficiency is low, but find in actual use, because conducting strip is due to by heating repeatedly, due to the reason of expanding with heat and contract with cold, in use for some time, easily there is gap and leak in the seam between conducting strip and cooling sheath body, electrode is discharged to coolant jacket, cause leaky, not only affect the quality of laser Output of laser, also brought potential safety hazard.
So, need at present one badly and facilitate processing, can prevent again the carbon dioxide laser coolant jacket of electrode to coolant jacket electric discharge.
