Embodiment Construction

[0021] The invention provides a high-power, high-pressure, large-volume, stable and uniform discharge electrode structure, which is characterized in that:

[0022] It is composed of a cathode (1), a ballast medium (2), a main discharge anode (3), an insulating medium (4), and a pre-ionized anode (5). One piece of ballast medium (2) and cathode (1), on one side of the discharge area, another piece of ballast medium (2) and the main discharge anode (3), insulating medium (4), and pre-ionized anode (5). The other side of the discharge area, and the pre-ionization anode (5) is at the outermost side. The insulating medium (4) is between the main discharge anode (3) and the pre-ionization anode (5). The periphery of the discharge area of ​​the cathode (1) is an improved Zhukovsky shape, composed of several thin copper plates, and both sides of each thin copper plate are plated with insulating dielectric layers. The main discharge anode (3), pre-ionization anode (5), insulating medium (4...

Abstract

The disclosed structure of electrode is composed of cathode, ballasting medium, main discharge anode, insulating medium and pre ionization anode. Comparing with current technique, the invention possesses advantages: even pre ionization, good quality of continuous discharging light beam, even distribution of electric field of electrode. The invention is applicable to continuously even stably discharge of crossing current carbon-dioxide laser in large power, high air pressure and large volume.

Description

Technical field: [0001] The invention provides a high-power, high-pressure, large-volume, stable and uniform discharge electrode structure, which belongs to the technical field of lasers. Background technique: [0002] High-power, high-pressure, large-volume, stable and uniform discharge is the core issue of cross-flow carbon dioxide lasers, with many influencing factors. One of the current domestic measures is to adopt pre-ionization technology. The commonly used pre-ionization electrode structure is as follows: [0003] 1. Tube-plate pre-ionization electrode structure: [0004] Cross-flow carbon dioxide laser tube type pre-ionization electrode structure (Cha Hongkui et al., tube-sheet type cross-flow 10KWCO 2 Experimental research on laser, China Laser, 1992, VO1.19, NO.10, 728~734), the cathode is a copper tube, and the inside is cooled by water. The anode is divided into dozens of small blocks, each block is connected in series with ballast resistors, and all of them are conn...
