Description
Technical field
The utility model relates to axial fast flow gas laser, particularly a kind of high power gas laser anode nozzle of air supply.
Background technology
Anode nozzle of air supply is the vitals of high power gas laser, it is arranged on the anode place of discharge tube 1, be provided with anode pin 2 and gas turbulence hole 3, during work, gas is driven quickly through discharge tube 1 by high-speed circulating blower fan, electrode at discharge tube 1 two ends produces and applies high voltage electric field, glow discharge is there is in working gas in chamber, produce gain media, in the resonant cavity that many groups discharge tube 1 and the eyeglass of high power gas laser form jointly, part energy produces Laser output, and another part produces thermal release.In discharge tube 1, the uniformity of the turbulent flow conditions of the flow of working gas, the uniformity of gain substance and gas determines the size of the light beam of laser, the stability of laser and laser power.
As shown in Figure 1 to Figure 3, be anode construction common at present.
Figure 1 shows that frontal inlet straight tube anode mechanism, gas enters discharge tube 1 by anode entrance, in straight length electric discharge work, after got rid of by outlet, the gas access 5 that the small air inlet hole (being gas turbulence hole 3) of straight tube and anode pin 2 form is nozzle of air supply.Actual use, turbulence effects, discharge tube 1 discharge effect of middle frontal inlet straight tube anode mechanism are better, but because resistance is large, its gas flow is less, usually to improve gas flow and must increase inlet diameter, but along with the discharge effect of the increase discharge tube 1 of entrance hole diameter worse and worse, can destroy electric discharge to during certain pore size.
Figure 2 shows that opposite air inlet straight tube anode construction, similar to Fig. 1, gas from gas entrance 5 enters anode needle stand 4, after walking around discharge tube 1, discharge tube 1 is flowed on the opposite of gas access 5, in straight length electric discharge work, after by outlet get rid of, the small air inlet hole of straight length, the circulation of anode needle stand 4 and anode pin 2 composition be nozzle of air supply.In actual use, the turbulence effects of opposite air inlet straight tube anode mechanism is better, and discharge tube 1 discharge effect comparatively Fig. 1 is good, but larger owing to streaming rear resistance, and more when young, under the same terms, laser power is a little less than Fig. 1 for its gas flow.
Fig. 3 is single hole anode cross discharge tube anode construction, in order to solve the little problem of straight tube throughput, discharge tube 1 is modified to cross, gas enters discharge tube 1 by anode nozzle, enter straight length via the commutation of cross structure gas and put a job, finally discharged by outlet, anode nozzle and cross tee structure form turbulent flow generator structure.The structure of single hole cross discharge tube 1 effectively can improve gas flow in actual applications, can 30%-40% be promoted relative to the formation gases flow of Fig. 1, Fig. 2, easily realize high power, but gas turbulence is not in good state, require very high to the leak rate of machine, air consumption.
