Problems solved by technology

[0003] First, the support structure of the one-dimensional waveguide is complex, the processing and assembly of parts are inconvenient, and the support materials are expensive and the amount used is large, which is uneconomical;
[0004] The second is that the support method is unreasonable. If the suspension (hanging) support method is used, it is difficult to ensure the parallelism between the large-area discharge surfaces, resulting in uneven suspension (hanging) of the waveguide spacing; Supporting the pad support of the side wall, which can simplify the installation and adjustment, but due to the large supporting area, it is difficult to ensure the flatness of the electrode plate support part or the parallelism between the upper and lower support surfaces of the pad support side wall, which makes the waveguide of the pad support The uneven spacing also affects the uniformity and stability of the discharge and the reliability of the laser device.
Therefore, there is still no technical solution to use the static concentrated electric parameters of the structure to smooth the dynamic change of impedance caused by gas discharge or ionization change, weaken the adverse effect of large impedance fluctuations on the RF power supply, and improve the discharge stability.
[0006] In addition, in the existing slab waveguide discharge structure, the confinement space of the waveguide and the completely free space of the vacuum cavity are either directly adjacent, or separated by side walls, or directly transitioned by a section of "wide" waveguide. This structure lacks more Effectively reduce the thermal radiation of the gas discharge plasma, so that the working gas stored in the vacuum cavity will heat up significantly, and the thermal radiation of the two-terminal waveguide port will cause thermal deformation of the resonant cavity mirror and other adverse effects

Abstract

The invention provides a cantilever support one-dimensional slab waveguide gas laser, which comprises a metal slab waveguide gas discharge structure disposed in a metal vacuum chamber and an optical resonator. The slab waveguide gas discharge structure comprises an upper electrode and a lower electrode which are disposed in parallel. The lower electrode is fixedly disposed on a substrate at the bottom of the metal vacuum chamber. The invention is improved in that the upper and lower electrodes are of the same structure and have an cross section shaped like an inverted Chinese character "Shan" and a cross section shaped like a Chinese character "Shan" respectively, with three bosses at the same height, the central portion is a waveguide discharge boss, the two sides are bases, and the recessed portions therebetween are rims; and the upper and lower electrodes are disposed in symmetry, and support members are disposed vertically between the bases. Compared with the prior art, the cantilever support one-dimensional slab waveguide gas laser provided by the invention has a simple and compact structure, improves the uniformity and stability of discharge and the smoothness of laser power output, is easier in part machining and assembling and lower in manufacturing cost, and facilitates mass production.

Description

technical field [0001] The invention relates to a slab waveguide gas laser, in particular to a cantilever supported one-dimensional slab waveguide gas laser. Background technique [0002] Since the advent of lasers in the 1960s, CO 2 Lasers have always played an important role, especially the combination of waveguide for gas discharge combined with radio frequency transverse excitation diffusion cooling, which has given birth to a new generation of high-power continuous output, high beam quality, and cost-effective gas laser---radio frequency excitation diffusion cooling metal plate Strip waveguide CO 2 laser. For half a century, the manufacturing technology of slab waveguide gas laser devices has experienced the evolution process of all-ceramics, cermet sandwich, and all-metal structures, and has developed from two-dimensional to one-dimensional by area-increasing ratio, volume-increasing ratio, and the inventors studied , Observation, and analysis on the basis of prior ...
