Abstract
The utility model relates to a copper steam laser with a power over a hundred watt, and the average power of the output laser beam exceeds a hundred watt. In the laser head of the utility model, a single shaping insulating medium layer which has thin middle and thick both ends is arranged between the laser discharge tube together with the discharge electrode at the both ends and a glass tube which is arranged outside the discharge tube and the shaft center; meanwhile, aerosphere is arranged between the glass cylinder and the high voltage insulating cylinder together with a water cooling circulating sheath; thus, compared with the prior art which adopts the structure of two kinds of a non shaping heat insulating medium layer and a vacuum thermal shield layer, the utility model has the advantages of simple structure, no pollution of medium to environment, no damage to operators, long service life of lasers, and enhancement of output power of lasers.
Description
The utility model is the copper vapor laser that a kind of average laser power reaches the above super hectowatt power of hectowatt.
Prior art:
(1) nineteen ninety Andrew Kearsley and (2) Shimpey Shirayama etc. have proposed to be added by the adiabatic medium of a kind of non-setting the high-power copper steam laser of the laser head that vacuum heat shielding layer structure form.
The laser head structure of the copper vapor laser that (3) 1992 years inventor Nobutada Aoki etc. propose as shown in Figure 1.There are periphery and its concentric of the laser tube 9 of sparking electrode 11 to be equipped with glass infuser 7 at built-in shot copper 15, two ends; Adiabatic dielectric layer 8 of the first non-setting and the adiabatic dielectric layer 16 of the second non-setting between discharge tube 9 and glass infuser 7, have been filled up; Refluxing between the cover 6 at glass infuser 7 and High-Voltage Insulation tube 5 together with water-cooled is vacuum heat shielding layer 14.Glass infuser 7 and High-Voltage Insulation tube 5 are vacuum seal by two many " O " shapes of flange 4 usefulness the sealing rings 3 of merely hitting with cathode taps 2 and anode head 10 respectively together with reflux two ends of cover 6 of water-cooled.Cathode taps, anode head bright dipping end window have all sealed glass plate 12.Place the plano-concave completely reflecting mirror 1 at laser head two ends to constitute laserresonator with output plane mirror 13.
The laser head structure that above-mentioned prior art proposed all is the heat insulating construction with two kinds of adiabatic dielectric layers 8,16 of non-setting and vacuum heat shielding layer 14, its complex structure, and the manufacture craft difficulty is big.And in making the process of laser head, when using the adiabatic medium of non-setting, cause severe environmental pollution, influence operating personnel's physical and mental health, and influence the useful life and the power output of laser.
The purpose of this utility model is the defective that overcomes in the above-mentioned prior art, simplifies the structure of laser head, eliminates the adiabatic medium of non-setting to the pollution of environment and operating personnel's murder by poisoning; And improve the useful life of laser and export laser power.
The laser head structure of the utility model laser as shown in Figure 3.Discharge tube 9 is built-in with shot copper 15, and the two ends concentric is equipped with respectively the sparking electrode 11 that is connected with anode head 10 with cathode taps 2.One end of anode head 10 and cathode taps 2 is vacuum seal by two merely hit flange 4 usefulness " O " shape sealing rings 3 with glass infuser 7 respectively, and anode head 10 and cathode taps 2 and High-Voltage Insulation tube 5 be together with the water-cooled needing no vacuum sealing-in between the cover 6 that refluxes, and is atmosphere 18 because of glass infuser 7 and High-Voltage Insulation tube 5 reflux between overlapping 6 together with water-cooled.Discharge tube 9 is together with being the adiabatic dielectric layer 17 of single setting of intermediate thin two ends thick (filling up intermediate space) between the sparking electrode 11 at two ends and the glass infuser 7, and the same envelope of the light-emitting window of laser head two ends has glass plate 12.Place the laser head two ends to have plano-concave completely reflecting mirror 1 and output plane mirror 13 to constitute laserresonator.
The utility model advantage is:
In the utility model laser head only with the adiabatic dielectric layer 17 of a kind of setting, and existing technology need be with two kinds of adiabatic dielectric layers 8,16 of non-setting, so the utility model has not only been saved a kind of adiabatic medium, simplify the structure and technology, and eliminated of the pollution of adiabatic medium operating personnel and environment.
2. got rid of vacuum heat shielding layer 14 in the prior art in the utility model laser head, not only further simplified the structure and technology, and the useful life of having improved laser, so that improve laser output power.
Description of drawings:
Fig. 1 is the structure chart of the high-power copper steam laser that proposed such as prior art (3) inventor Nobutada Aoki.
Fig. 2 is the structure chart of the copper vapor laser of super hectowatt power of the present utility model.
Embodiment:
Structure as shown in Figure 2, the cathode taps 2 of its laser head, anode head 10, middle flange 4, water-cooled backflow cover 5 are made for stainless copper product entirely; Glass infuser 7 is internal diameter 14.6cm, the cylinder of quartz glass of long 245.8cm; Discharge tube 9 is internal diameter 6.5cm; The high-purity ceramic pipe of long 220cm is placed 5～10 gram shot coppers in the discharge tube 9.Be equipped with between discharge tube 9 and glass infuser 7 by the adiabatic dielectric layer 17 of the ceramic fibre of ALC setting, two ends of this adiabatic dielectric layer 17 are thicker, and the centre is thinner, in order that the axial temperature of discharge tube 9 inwalls can be remained on more than 1000 ℃ equably.Before the discharge, be pumped into 3～5 * 10 in advance in the cylinder of quartz glass
-4The vacuum of torr is filled the Ne gas of 10～30 torrs then.Electrode 11 is the copper tube electrode of internal diameter 6.5cm.Laser reaches 110 watts at 510.6nm and 578.2nm laser average output power green and yellow two wavelength places, and green glow is 2: 1 with the ratio of the deal of gold-tinted, and the pulsewidth of each laser pulse is 40ns, and peak power is greater than 500KW.Under similarity condition, laser power is much improved than prior art.
