In sealed lasers, catalytic technology can effectively extend the life of the laser. CO2 at high voltage excitation .The practical application of the laser tube is that the life of the coated catalyst does not exceed 3000 hours, and the service life of the catalyst laser tube is extended to more than 8000 hours. Analysis of the specific role and principle of catalytic JH 80W CO2 laser tube

Taking the high-voltage excitation of a JH 80W CO2 laser tube as an example, the outer edge of the plasma can be regarded as the energy of the inner wall of the discharge tube.

 

Coated with a catalyst. Under high voltage excitation, the carbon dioxide gas molecules in the discharge tube are continuously decomposed, and the CO2 is decomposed into CO + O under electron collision. Fortunately, the reaction process is reversible, and CO and O combine to form carbon dioxide after meeting each other. But the complexity of this encounter is incomplete, because the probability of encounter is not less than the decomposition process of carbon dioxide. More serious is JH 80W CO2 laser tube that the complex oxygen atoms are combined to form O 2 , and the reaction ability of O 2 and CO is very high, and it is difficult to recombine and form carbon dioxide. The O2 molecule is very active and can generate oxides with other gas molecules in the device. Various oxides are very deadly to JH 80W CO2 laser tube, which can greatly reduce the output power of the laser. Oxidation and accumulation, to a certain extent, can cause a chain reaction to disappear in the laser power for several hours. The hot spot of this work is that the laser power does not decrease linearly after a period of time, and suddenly there is no light. Based on the above analysis, the core solution is to accelerate carbon dioxide recombination and reduce activation energy. Then you have to use a catalyst. A specific method is JH 80W CO2 laser tube to coat the catalyst on the edge of the plasma. The material of the catalyst can be classified into metal or rare earth.

 

The metal content in Au can play a significant catalytic role in Cu. However, there is a disadvantage in that the metal is an excellent conductor, and the metal is directly electroplated on the discharge tube, and the current is directly transmitted through the membrane instead of being conducted through the gas, so discharge excitation is impossible. A solution to this problem is to apply a metal oxide to the inner wall of the discharge tube. Therefore, the emission problem is well solved for catalytic purposes.
