Abstract

The invention discloses a combined CO2 laser tube. The combined CO2 laser tube comprises a gas storage tube, wherein a total-reflection lens seat and a window lens seat are arranged on the gas storagetube, the total-reflection lens seat is provided with a total-reflection cavity, the window lens seat is provided with a window cavity, a plurality of discharging tubes are arranged between the total-reflection lens cavity and the window cavity and are connected in an end-to-end way, a turn-back lens seat is arranged between two adjacent discharging tubes, a window coupling lens is arranged in the window cavity, each discharging tube is placed in a water-cooling tube, a positive electrode is arranged on a connection piece at one end of the discharging tube, a negative electrode is arranged ona connection piece at the other end of the discharging tube, the total-reflection lens cavity, a turn-back cavity and the window cavity communicate with the gas storage tube via a gas return tube, and a gas discharging hole is arranged in the gas storage tube. The combined CO2 laser tube is good in stability, and a precondition is provided for improving a laser power by employing the plurality ofdischarging tubes.

Description

technical field [0001] The present invention relates to CO 2 The technical field of laser tubes, in particular to a combined CO 2 Laser tube. Background technique [0002] CO 2 Due to the irreplaceability of laser tubes in the field of non-metallic material processing, their market potential is huge, especially for medium and high power CO 2 In recent years, the market demand for laser tubes has grown several times each year. [0003] Currently, there are three types of medium and high power CO 2 Laser tube: one type is radio frequency excitation laser, which is expensive and complex in technology, and only a few companies in the United States and Germany can produce it; the second type is axial block flow laser, due to its production process and technical route, only high power can There are cost-effective and competitive advantages, and the cost of use is relatively high; the third type is a folding CO2 made of pure glass. 2 Due to the characteristics of the glass, t...
