Preparation method of high-voltage infrared type carbon dioxide laser tube

Abstract

The invention relates to a preparation method of a high-voltage infrared type carbon dioxide laser tube. The preparation method of the high-voltage infrared type carbon dioxide laser tube comprises the following steps of: preprocessing of two liquid resin cavity layer bottom plates which are parallelly arranged inside; processing of a plurality of substrate film cavity layer intermediate plates which are equidistantly arranged inside; and processing of a plurality of glass fiber grating layer top plates which are horizontally arranged inside. With the uniquely and innovatively-designed preparation method adopted, technical problems such as complex structure, low accuracy, large optical fiber folding offset, low performance stability and complex adjustment of a carbon dioxide laser in the prior art can be solved. The preparation method of the high-voltage infrared type carbon dioxide laser tube is advantageous in reliable use, greatly-improved stability, high precision, simple and convenient adjustment, small size, light weight, being not affected by temperature change, and can greatly reduce strength loss in light beam translation and rotation change.

Description

technical field [0001] The invention relates to the technical field of laser tubes, in particular to a method for preparing a carbon dioxide laser tube, and more specifically to a method for preparing a high-pressure infrared carbon dioxide laser tube. Background technique [0002] The market potential of carbon dioxide laser tube is huge. In recent years, the market demand has been increasing geometrically every year. It is widely used in various industries for cutting, drilling, engraving, marking, quenching, cladding and welding of non-metallic and metal materials. And other laser processing. [0003] At present, there are two types of small and medium power carbon dioxide lasers on the market, one is a radio frequency excitation metal tube, referred to as a radio frequency tube, and the other is a direct current excitation glass tube, referred to as a glass tube. RF tubes can meet the market's precision requirements for laser processing, but the price is extremely expen...
