Description
Technical field
The present invention relates to field of lasers, more particularly to a kind of sealed CO 2 laser.Laser is can be applied to cut
Cut, in the equipment such as engraving.
Background technology
In current middle low power seal-off carbon dioxide laser field, mainly it is divided to two big structures, a kind of wire chamber
RF excited carbon dioxide laser, this laser production cost is high, is mainly used in laser marking；Another glass discharge vessel
The high direct voltage electric excitation carbon dioxide laser of structure.China Patent Publication No. CN2862437 is looked into, its entitled off two
Carbon oxide laser device, it is so described：A kind of seal-off carbon dioxide laser, has and water is set in gas-storing pipe, gas-storing pipe
Cold pipe, water cooling tube is connected with inlet tube and outlet tube, and discharge tube is set in water cooling tube, and positive electrode is arranged in the cavity of discharge tube one end,
Total reflective mirror is set on the outside of the cavity, and negative electrode is arranged in the cavity of the discharge tube other end, output reflection is set on the outside of the cavity
Muffler is installed around on mirror, water cooling tube, one end of muffler is communicated with gas-storing pipe, the muffler other end and the sky for being provided with positive electrode
Chamber is communicated.The laser with more earlier glass tube laser ratio on the market without evident characteristic and advantage, its structure and
The laser sold in the market all has a disadvantage that：Total reflective mirror and outgoing mirror are all directly bonded in glass by current lasers
The glass mouth of pipe, and the grinding precision of the mouth of pipe is extremely difficult to be expected requirement, makes product quality uniformity not high, power output and pattern
It also is difficult to be in optimum state.The gas storage pipe diameter of current lasers is all below 65 millimeters, and gas-storing capacity is fewer, causes device
Service life it is not long.Current lasers negative electricity polar ring is all crimped onto electric discharge inside pipe wall using sheet metal, and negative electrode is in electric discharge
Temperature is very high, and when cooling current are not smooth, electrode temperature steeply rises, and the rapid glass material that high temperature is passed to electrode retaining collar side
Material, causes the extreme differential expansion of glass discharge vessel negative electricity and bursts, make device failure.The positive electrode of current lasers is all adopted
Electric discharge inside pipe wall is crimped onto with sheet metal, in the presence of electric field, positive electrode transmitting cation is moved to negative pole, is reached at it
Just become neutral particle during negative electrode after trapped electron, so there was only localizing electrode's material in action during positive electrode electric discharge, root
According to discharge characteristicses, energy is only gathered in the dot near the positive electrode chip edge of negative electricity extreme direction, and electrode is thin slice
It is rolled into, then this point of discharge excites area just less, and the energy of this point acts on just higher, the stability of electrode material
Just reduce.The electrode of current lasers is all to be introduced electric current by the metallic rod being sintered on glass shell, sintering process
Difficulty is high, but laser device requires high to vacuum sealing, so product qualification rate is difficult to improve, and such structure works as electrode
When neighbouring eyeglass is semiconductor or conductor, electrode can discharge eyeglass, destroy eyeglass film layer, with influenceing product stable to use.
China Patent Publication No. CN101262112 is looked into, a kind of its entitled CO 2 laser with new structure, it is so
Description：Laser outgoing mirror is not directly to be bonded in the glass mouth of pipe, but outgoing mirror is bonded in the one of angle demodulator
End, the other end and counter flange piece of angle demodulator weld together, then counter flange piece and glass mouth of pipe asphalt mixtures modified by epoxy resin
Fat glue is sealed.Angle demodulator is manufactured with elastic preferably stainless steel material, in the centre of angle demodulator by extroversion
Adjusting grooves are inside provided with, another adjusting grooves are provided with from inside to outside in the place close to this groove, the tune opened in ecto-entad
The periphery of section groove is provided with the set screw of more than three, set screw is absorbed by the elasticity of adjusting grooves tight fashionable
Tension force, so as to change the angle of outgoing mirror.The total reflective mirror of laser is nor be directly bonded in the glass mouth of pipe, but handle is all-trans
Mirror is bonded on the regulating flange of a pair of edge of a knife flanges, and in order to which regulating flange does not make lens deformation when adjusting eyeglass, increase is adjusted
The mechanical strength of flange is saved, an outwardly part is wanted in the abutting edge of eyeglass at the regulating flange back side, the another of edge of a knife flange
In semifixed flange and counter flange piece welding, then counter flange piece and the glass mouth of pipe with epoxide-resin glue sealing-in.Solid
Determine to press from both sides a soft metal packing ring between the edge of a knife of flange and the edge of a knife of regulating flange, soft metal packing ring available copper, aluminium, the metal such as silver
Manufacture, compresses soft metal packing ring, changing the angle of total reflective mirror by adjusting the degree that tightly enters of clamping screw of different azimuth.
The shortcoming of above content is also resided in all realizes eyeglass and canals of stilling or eyeglass and metal using gluing mode
The connection of flange, metal flange and canals of stilling.Traditional sealed CO 2 laser is the output composition resonator
Eyeglass and total reflection eyeglass are pasted canals of stilling or adhered on metal flange and adhered to again by metal flange on canals of stilling respectively.This
The laser of two kinds of structure structures, needs first to reach the glass mouth of pipe by manually carefully grinding again by machine corase grind in manufacturing process
Use requirement can be reached by being parallel to each other to both ends of the surface.Due to the different end surface grindings of everyone ability during underhand polish
Time is general 10-20 minutes, and requires all very high to artificial naked eye vision, technical ability qualification, past under such condition
Toward there is also the phenomenon that optical axis deviates with resonator geometrical central axis and is not orthogonal to resonator eyeglass, it is difficult to ensure that two humorous
Hysteroscope of shaking piece constitutes the relative position relation of optical resonator requirement.Two resonator eyeglass relative position relations are to determine laser
Export laser power, hot spot（Pattern）Principal element.Conventional carbon dioxide laser because from eyeglass to metal flange again to glass
When glass body is with glue sealing-in, glue curing needs certain condition such as temperature and time, and high-quality glue needs higher
Price, and viscose glue ratio also can to properties of product start restriction effect, glue easily cause in itself intracavitary volatilization pollution chamber
Mirror, glue can also discharge foreign gas to cause working gas to pollute under high-pressure high-temperature environment, and reduction laser uses the longevity
Life.Glue or disposable running stores simultaneously, such as because operational error can also caused by metal flange and eyeglass scrap, causing need not
The loss wanted.Technical difficulty is big, it is difficult to produce in batches, it is impossible to meet the need for market increasingly increases.
The content of the invention
It is an object of the invention to provide a kind of sealed CO 2 laser, the above-mentioned of prior art presence is solved
Problem.Structure of the present invention is reliable, and convenient for production, power output high light beam quality is good, and service life is long.Laser of the present invention it is defeated
The eyeglass for going out end and radiation end is not to be fixed on by gluing mode on laser canals of stilling, is by canals of stilling
