Embodiment
A kind of CO
2laser, comprises a laser vacuum cavity, includes discharge system and gas circulation cooling system in laser vacuum cavity; Wherein gas discharge system is made up of main discharge electrode and pre-ionization electrode; Gas circulation cooling system is made up of gas circulation blower fan and heat exchanger.Described laser cavity adopts stainless steel material precision welding to form.Described main discharge electrode and pre-ionization electrode, between gas circulation blower fan and heat exchanger, combination part is tightly connected by high vacuum silicon rubber loop.Described main discharge electrode adopts the Zhang Shi electrode after improving; Electrode material selects 45# carbon steel, main discharge electrode spacing 10 mm, electrode width 10 mm, electrode length 120 mm.Also optical resonator is provided with in described gas discharge system.
Main discharge electrode adopts the Zhang Shi electrode after improving, and be the discharge instability avoiding cathode surface sputtering under high repetition frequency condition to cause, electrode material selects 45# carbon steel, main discharge electrode spacing 10 mm, electrode width 10 mm, electrode length 120 mm.In order to reduce the volume of laser while effectively improving electric discharge gain volume, preionization assembly adopts quartz glass tubulose UV corona preionization structure, is fastened on the both sides of main discharge negative electrode.Before main electrode electric discharge, the leading non-self-maintained discharge of preionization, the portion gas be positioned between main electrode is ionized, and between negative and positive two main electrode, form uniform electric field, inter-electrode impedance declines rapidly, and then obtains uniform and stable main electrode glow discharge.
Laserresonator adopts typical flat-concave cavity structure, and Effect of Back-Cavity Mirror is the surface gold-plating total reflective mirror of the oxygen-free copper substrate of radius of curvature 4 m, and outgoing mirror is the ZnSe level crossing of fractional transmission.Owing to adopting corona preionization mode, Laser output gain in resonant cavity is lower, outgoing mirror adopts the technique of double-sided coating, and the working face inside chamber plates wavelength centered by 10.6um and reflectivity is the rete of 60%, the anti-reflection film of face plating wavelength centered by 10.6 um outside chamber.In order to improve the beam quality of Output of laser further, in chamber, install limit mould diaphragm additional near the position of outgoing mirror, to obtain the Laser output of low-order mode.
Laser Devices adopt high-speed turbine booster fan to obtain the air-flow of high-speed circulating, by optimizing the structure in air channel, can reduce the pressure loss, make air-flow stable when flowing through region of discharge, even.The redundancy heat that gas discharge produces can deposit and be discharged into its exterior environment by heat exchanger effectively.
