Description

The purity of the component gas in the laser mixture directly affects the performance of the laser, especially the presence of impurities such as oxygen, water and hydrocarbons in the gas will lead to the loss of laser output power on the mirror (surface) and electrode, but also cause the instability of laser emission. One of the important characteristics of the gas laser, the laser working material is mixture or a single pure gas, therefore, there are special requirements for the purity of the laser mixture components, the cylinder packaging mixture, before filling must also be dried to prevent pollution of the mixture.
