Problems solved by technology

It can ensure that the laser can obtain a stable and uniform glow discharge under the condition of high working pressure and high gas flow rate. Although the output power and working life of the laser have been improved compared with the previous ones, due to the limitation of the structure of the discharge electrode , it is difficult to greatly increase the output power of the laser
In prior art 2, the patent ZL99252127.0 provides a carbon dioxide laser with large energy and wide pulse width. Although the output power of the laser has been greatly improved, it is difficult to increase the injection power and laser output power.

Embodiment Construction

[0018] like figure 1 The structure shown at the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, 5 kW cross-flow CO 2 implemented on the laser. CO in this example 2 The laser adopts dual axial fans (rotational speed 8000 rpm), dual discharge channels, and ∏-shaped folded cavity. like figure 1 The discharge area shown is divided into inner and outer sides. The length of the anode strips 801 is 50mm, the width of the anode strips 801 is 15mm, the distance between the anode strips 801 and the strips is 5mm, the anode strips 801 are embedded in the insulating plate 802 formed by the high temperature resistant insulating material, and are arranged in a row of the same plane . There are 57 anode strips 801 in each discharge area, and the effective discharge length is 1140mm. The one-to-one correspondence with each anode strip 801 is: the pulse pre-ionization needle 7 is made of Φ1mm copper needles, and the number of columns of the cathode needles 1...

Abstract

The needle-stripe electrode pulse pre-ionization transverse current CO2 laser discharge cavity is characterized by that in the discharge cavity the anode is composed of the anode stripes which are arranged into one column, muturally insulated and inlaid on the insulating plate, and its pre-ionization electrode is composed of pulse pre-ionization needles which are arranged into one column and one-to-one correspondent to the above-mentioned anode stripes. The cathode needle and pulse pre-ionization needle are directed against anode stripe, and their tail ends are inserted into the liquid cell with flowing liquid, and between tail ends of two needles and two terminals they are connected by means of liquid resistance. It features large injection power and high autput laser power.

Description

technical field [0001] The invention is a kind of needle bar electrode pulse pre-ionized lateral flow carbon dioxide (CO 2 ) laser discharge cavity for boosting cross-flow CO 2 The price-performance ratio of the laser. Background technique [0002] High Power Crossflow CO 2 Lasers are widely used in steel, petroleum, automobile manufacturing and other industries. Its main advantage is that its continuous output and repetitive pulse output power are high, and the average power is generally between kilowatts and 10,000 watts, and higher power output can also be obtained. From the first cross-flow CO 2 Over the past 30 years since the birth of the laser, scientists have been working on the improvement of the discharge electrode structure, constantly seeking to obtain more electrical power injection per unit activation volume, under the condition that the electro-optical efficiency is basically the same (usually between 10% and 20%) , so as to obtain higher laser power outp...
