Description

Totally-enclosed CO 2 efficient laser tube Technical Field The invention relates to the technical field of laser tubes, in particular to a totally-enclosed CO 2 high-efficiency laser tube. Background The carbon dioxide laser is a gas laser that generates laser radiation by carbon dioxide, and a direct current is supplied to a discharge tube, so that nitrogen molecules in a mixed gas in the discharge tube are excited by the impact of electrons during discharge. At this time, the excited hydrogen molecules collide with the CO 2 molecules, and the N 2 molecules transfer their own energy star to the CO 2 molecules, so that the CO 2 molecules transition from a low energy level to a high energy level to form a population inversion, thereby generating laser light. Therefore, carbon dioxide laser tubes are one of the most widely used lasers at present, and are widely used in the fields of material processing, medical treatment, environmental measurement and the like. Through mass search, the prior art with the publication number of CN203193110U is found, and a carbon dioxide laser tube is disclosed. The utility model effectively reduces the dependence of the lens mounting precision on the pipe orifice grinding precision, improves the position precision of the total reflection mirror, the output reflection mirror and the discharge pipe by adjusting the angle of the lens, and improves the quality of the carbon dioxide laser pipe. Through increasing the gas storage capacity, using a catalyst and using an anode electrode welded with noble metal wires, the stability of the carbon dioxide laser tube is improved, the service life is prolonged, and the service life can reach 10000 hours. A finished cathode electrode was used. And the glass is better attached to the discharge tube, so that the glass burst caused by uneven heating is reduced. In summary, in the practical application process of the existing carbon dioxide laser tube, since the length of the carbon dioxide laser tube determines the laser reflection travel, the longer the length of the carbon dioxide laser tube is, the higher the output laser power is, and the length specification of the existing carbon dioxide laser tube is fixed, which results in inflexibility in terms of adjusting the laser power, and the laser is reflected in the discharge tube, the laser convergence is low, the laser beam output from the negative electrode terminal only occupies a small part of the laser generation amount in the discharge tube, and the laser output is not comprehensive and converged.
