Description
The utility model belongs to laser technology field.
As everyone knows, gas laser is a kind of common Laser Devices, and during work, it can emit a large amount of heats, untimely these heats of draining, to some gas laser (as CO
2, CO, A gamma-ray laser device) be not fill to be permitted.At present, be extensive use of circulating water refrigerating gas laser, i.e. water-cooled gas laser.
The water-cooled gas laser has following shortcoming: 1, work is inconvenient, needs water-cooled during because of laser works, and in the lack of water occasion, this type of laser just can't be worked.2, work is dangerous.During laser works,, can cause that all laser bursts if water flowing is not in time cooled off or unexpected interruption of supplying water.3, need certain refrigeration costs and attachment device.
In order to overcome above-mentioned shortcoming, people realize that to gas laser anhydrous cooling work carried out research and inquirement in large quantities, but do not see the open report of this work success so far.
The purpose of this utility model is to propose a kind of anhydrous refrigerating gas laser with practical value, makes it be used in various occasions conveniently, effectively, safely.
Realize that anhydrous refrigerating gas laser of the present utility model comprises cooling device and the laser tube of being made up of discharge tube (5), two chamber mirrors (3), (4), its key problem in technology is to use the cooling device of heat-pipe apparatus as laser.Its essential structure is as follows:
Discharge tube (5), radiating tube (6) and capillary materials (7) and hydraulic fluid have constituted heat-pipe apparatus.Discharge tube is as the hot junction of heat-pipe apparatus, and radiating tube is as the cold junction of heat-pipe apparatus, and capillary materials is attached on the inwall of discharge tube outer wall and radiating tube, and hydraulic fluid is contained in the heat-pipe apparatus, makes it soak capillary materials.Whole heat-pipe apparatus is realized vacuum seal.
In the heat-pipe apparatus, discharge tube (hot junction) adopts eccentric structure or concentric structure with the relative position of radiating tube (cold junction).When using eccentric structure, can strengthen the phase variable area, reduce hydraulic fluid.
Hydraulic fluid is selected ethanolic solution, acetone soln and ionized water for use.In general, though water helps conduction and high power, but heat balance time is longer, after adding ethanol or acetone soln, can shorten the stable operating time of laser tube effectively, simultaneously, help reducing the temperature of hydraulic fluid, so thereby also improve the power of laser because the acetone or alcohol gasification temperature is low.
Capillary materials can be selected the woven wire of high order number according to the wettability of hydraulic fluid for use, as copper mesh, steel wire, titanium wire network, also can select glass fibre or nickel fiber for use.
Radiating tube is made by the metal material of good heat conductivity, and its material is according to selecting copper, nickel or stainless steel for use with the compatibility of hydraulic fluid.
Press the heat pipe operation principle, when discharge tube is heated, be attached to the just evaporation of hydraulic fluid in the capillary materials on the discharge tube tube wall, steam flow is to the radiating tube tube wall, be subjected to cooling and make devaporation become liquid, liquid is got back in the capillary materials on the discharge tube tube wall by the effect of capillary force.So circulation, heat is passed on the radiating tube by discharge tube, is passed in the ambient air by radiating tube again.So just satisfy the heat radiation requirement of discharge tube, reached anhydrous cooling purpose.
Adopt the gas laser of above-mentioned cooling device, realized the operate as normal under the anhydrous situation, such gas laser was both easy to use, and was safe and reliable again, and compared with the water-cooled gas laser, also reduced refrigeration costs, reduced attachment device.
Below in conjunction with accompanying drawing 1, the utility model will be further described for accompanying drawing 2 represented embodiment.
Accompanying drawing 1 is not for being welded with the anhydrous refrigerating gas laser structure schematic diagram of fin.
(1) is that anode, (2) are that output germanium level crossing, (5) are sealing-in place of radiating tube and discharge tube for radiating tube, (7) for capillary materials, (8), (9) for discharge tube, (6) for negative electrode, (3) for completely reflecting mirror, (4) among the figure.
Accompanying drawing 2 is the end view of several different structures of anhydrous refrigerating gas laser cooling device.
(5) are that discharge tube, (6) are capillary materials for radiating tube, (7) among the figure.
In accompanying drawing 1, discharge tube (5) outer wall and radiating tube (6) inwall are with capillary materials copper mesh (7).Radiating tube (6) is the pipe made from copper sheet, and radiating tube and discharge tube sealing-in place (8), (9) are adopted and can be cut down matched seal, to guarantee the sealing property of different materials sealing-in, again cooling device are carried out vacuum exhaust afterwards, reach vacuum degree 10
