Embodiment Construction

[0017] As shown in FIG. 2 , the present invention relates to a high-voltage ceramic lead rod capable of withstanding high-power radio frequency pulse peak power, which consists of a ceramic part 1 and a lead rod 2 .

[0018] The ceramic part 1 is in a "T" shape, and is composed of a ceramic disc 6 with a central hole 7 and a ceramic cylinder 4 extending downward from the lower end of the ceramic disc 6 to form an integral structure.

[0019] The lead rod 2 is a silver-plated copper rod.

[0020] The lead rod 2 passes through the inner hole 5 and the central hole 7 of the ceramic part 1 , and the two ends of the lead rod 2 extend out of the ceramic part 1 .

[0021] The inner hole 5 at the lower end of the ceramic cylinder is metallized to form a layer of metal layer 3, and the ceramic cylinder 4 is silver-copper welded with the lower part of the lead rod 2 through the metal layer 3, and the center hole 7 of the ceramic disc 6 The hole wall is no longer metallized. There is a ...

Abstract

The present invention relates to a high-voltage ceramic wire leading rod which is resistant to high-power RF pulse peak power and used for RF slab CO2 lasers, which comprises a ceramic part (1) and a wire leading rod (2). The ceramic part (1) is in a T-shaped structure, which is an integral structure formed by a ceramic disk (6) with a center hole (7) and a ceramic cylinder (4) extending downwards from the lower surface of the ceramic disk (6); the wire leading rod (2) passes through an inner hole (5) and the center hole (7) of the ceramic part (1); the wall of the inner hole (5) at the lower end of the ceramic cylinder (4) is provided with a metal layer (3); the ceramic cylinder (4) is welded with the lower part of the wire leading rod (2) through the metal layer (3); a clearance is arranged between the wall of the center hole (7) of the ceramic disk (6) and the outer edge of the wire leading rod (2); a clearance is arranged between the wall of the inner hole (5) of the ceramic cylinder (4) and the outer edge of the wire leading rod (2) as well. Under the conditions of guaranteeing no change on the prior overall dimension of a laser shell, the present invention can prevent the surface of the wire leading rod from striking fire when the RF pulse energy with identical average power, identical frequency and exponentially increased pulse peak power is input.

Description

technical field [0001] The invention relates to a radio frequency slat CO 2 lasers, especially related to a radio-frequency slat CO 2 High voltage ceramic lead rods for lasers. It belongs to the field of laser technology. Background technique [0002] RF Slat CO 2 The laser is created by injecting radio frequency power into the laser to create a glow discharge. Generally, the RF source is connected to the ceramic lead rod of the laser through a coaxial cable. Ordinary ceramic lead rods are made of a silver-plated copper rod with Al 2 o 3 The ceramic discs are sealed together, as shown in Figure 1. The outer edge of the ceramic disk forms a vacuum connection with the shell of the laser, the upper end of the lead rod is connected with the coaxial cable, and the lower end is connected with the discharge electrode of the laser. This high-voltage ceramic lead rod can work reliably under the excitation of high-power RF continuous wave, but when the RF pulse excitation of t...
