Abstract
The utility model relates to the technical field of lasers, more particularly to a half flow type high strength carbon dioxide laser, which comprises a carbon dioxide storing pipe, a water cooling pipe and an electricity discharging pipe; all these components are orderly sleeved from the outer part to the inner part of the laser. The electricity discharging pipe is provided with a positive electrode and a negative electrode at both ends; the carbon dioxide storing pipe is provided with a water inlet pipe and a water outlet pipe which are communicated with the water cooling pipe. The water inlet pipe is arranged on the water cooling pipe at a place near the end part of the said positive electrode. The water outlet pipe is isolated from the water cooling pipe near the end part of the said negative electrode. In comparison with the water inlet pipe and the water outlet pipe, the laser is respectively arranged at the two ends of the water cooling pipe. The laser of the utility model allows the water inlet pipe and the water outlet pipe to be spaced at some reasonable distance away at the ends near the positive end. Arranged in this manner, the spanning distance between from the water inlet pipe and the water outlet pipe to the water cooling pipe is reduced. Further, the bending degree of the water cooling pipe is reduced when the laser undergoes a great impact force. As a result, the anti-impact capacity of the water cooling pipe increases, which further means the increase of anti-impact capacity of the carbon dioxide laser.
Description
Technical field
The utility model relates to field of lasers, particularly a kind of half reverse-flow type high strength carbon dioxide laser.
Background technology
Because carbon dioxide laser has larger power and higher energy conversion efficiency, spectral line is also abundanter, has the Laser output of tens spectral lines near 10 microns, is all widely used at aspects such as industry, military affairs, medical treatment, scientific researches.
Current carbon dioxide laser, generally include discharge tube, be set in the water cooling tube of discharge tube outside, be set in the cylinder of water cooling tube outside, the negative electrode that is separately positioned on discharge tube two ends and positive electrode and be arranged on output window and the reflection window at cylinder two ends, reflection window includes reflecting optics and reflecting optics cooling device, output window includes output eyeglass and output eyeglass cooling device, fills with carbon dioxide and other assist gas in discharge tube; When add high voltage on electrode time, in discharge tube, produce glow discharge, after reflecting optics and output lens reflecting, form laser beam, from output eyeglass, penetrate and obtain final laser beam.
It is good cooling for discharge tube is obtained, so sheathed water cooling tube outside discharge tube, a water inlet pipe and outlet pipe are set respectively on water cooling tube, one end of water inlet pipe is through cylinder and water cooling tube internal switching, the other end is placed in outside and the cooling water water source of cylinder and connects, one end of outlet pipe is also through cylinder and water cooling tube internal switching, the other end is also placed in the outside of cylinder and also connects with water source, between water source and cooling water pipe, form recirculated water like this, in the time of laser works, cooling water is pumped in water cooling tube from water inlet pipe, cooling water is back to external water source from outlet pipe after water cooling tube, and then realize cooling to water cooling tube, for the cooling water in water cooling tube is flowed completely, arrive good cooling effect, described water inlet pipe and outlet pipe are arranged in the end, two ends of water cooling tube, cooling water is entered from water cooling tube one end, then flow out from the other end, cooling water in whole water cooling tube can both exchange with external water source, and then reach good cooling effect.
In water cooling tube and discharge tube structure, water cooling tube end near positive electrode is fixedly connected with cylinder and connects with outlet pipe, and be hanging shape and connect with water inlet pipe near the water cooling tube end of negative electrode, so water inlet pipe and outlet pipe not only play a part Inlet and outlet water, yet play a part to support fixing cooling water pipe and discharge tube, so current water cooling tube is connected and is fixed in cylinder with water inlet pipe and outlet pipe respectively by its two ends with discharge tube simultaneously, because carbon dioxide laser is slim-lined construction, its water cooling tube is also slim-lined construction, the water cooling tube of two end supports has longer span like this, and, at storage warehouse-in, when moving transport and using, carbon dioxide laser is all the placement that is the level of state conventionally, so the water cooling tube between water inlet pipe and outlet pipe is owing to being subject to the impact of himself Action of Gravity Field and bending, produce larger winding degree, the existence of this degree of disturbing greatly, structural stability and the service precision of carbon dioxide laser are not only reduced, particularly in the time moving transport, in the time that packing case is subject to impacting, when impact is delivered on carbon dioxide laser, water cooling tube between water inlet pipe and outlet pipe is further bent, winding degree further increases, in the time that degree of crook is excessive, there is to destroy fracture in water cooling tube, cause carbon dioxide laser to damage.
So, need badly at present and a kind ofly can either make the cooling discharge pipe that water cooling tube is good, can improve again the carbon dioxide laser of water cooling tube impact resistance.
Utility model content
The purpose of this utility model is: for existing carbon dioxide laser above shortcomings, provide a kind of carbon dioxide laser that can improve water cooling tube impact resistance.
