The sealed Co2 laser tube 80w 100w 150w for laser machine is mainly composed of three parts: hard glass, resonant cavity and electrode.Hard glass part: This part is composed of a discharge tube made of Gg17 material, a water-cooled tube, a gas storage tube and a return air tube. Sealed Co2 laser tube 80w 100w 150w for laser machine are typically three-layered casing structures. The innermost layer is the discharge tube. The second layer is a water-cooled casing, and the outermost layer is a gas storage pipe. The thickness of the discharge tube mainly determines the diffraction effect caused by the spot size. The length of the discharge tube is proportional to the output power, and the output power increases as the length of the discharge tube increases within a certain range. The function of the water-cooled tube is to cool the working gas to stabilize the output power. The discharge tube is connected to the gas storage tube at both ends, that is, one end of the gas storage tube has a small hole communicating with the discharge tube, and the other end is connected to the discharge tube through the spiral return air tube, so that the gas can be circulated in the discharge tube and the gas storage tube. The gas in the discharge tube is exchanged at any time.
Resonator section: This part consists of a full mirror and an output mirror. The full mirror of the resonant cavity is generally based on optical glass and silicon (Si), and adopts a large curvature flat cavity. The radius of curvature of the concave mirror is R=2~3L surface gold film, MMR film, and the mirror is near 10.6um. The reflectivity of the resonant cavity is more than 99.8%; the output mirror of the resonant cavity is generally made of an infrared material (Ge) and zinc selenide (Z n Se) which can transmit 10.6 um of radiation, and the surface is made of a multilayer dielectric film. Length of discharge tube: l=Pw/Wo total length L=I+2△l, △I is 5-15% of total length; discharge tube diameter D: for base diaphragm operation, D=3ω concave multimode output: D The total loss of ≥ 4ω concave cavity α = αm + αmn.
Electrode part: Co2 laser tube 80w 100w 150w for laser machine generally adopts cold cathode and has a cylindrical shape. The choice of cathode material has a great influence on the life of the laser. The basic requirements for the cathode material are: low sputtering rate, low gas absorption rate, and commonly used metal. The material is nickel. The electrode length matching can suppress the further expansion of the instantaneous arcing, and can stably discharge when the working temperament deteriorates.Instructions
1. First connect the wire of the electrode, and (+, -) should not be connected incorrectly.2. The cooling water pipe is installed. The installation method is to enter the water from the negative electrode, the positive electrode is out of water and meet the principle of going in and out, and the interface cannot leak water. Before use, the water must be stored in the water reservoir. After the water is passed, the water-cooled tube must be free of air bubbles before use (you must check it before each use). If the Co2 laser tube 80w 100w 150w for laser machine is mounted vertically, please note that there are no air bubbles at the top of the Co2 laser tube 80w 100w 150w for laser machine, and operation in the presence of air bubbles will cause thermal shock, which will cause damage to the Co2 laser tube 80w 100w 150w for laser machine.3, Co2 laser tube 80w 100w 150w for laser machine efficiency is about 15-30%, so about 100 watts of laser power, about 200-500 watts of electrical energy will be converted into heat, in order to maintain the good performance of the laser tube, please use between 15-25 The temperature of the Celsius can be controlled by the chiller. The water flow speed should not be less than 2-4L/min. If the cooling water is unstable, the laser tube skipping mode and the spot shape output power will be unstable.4. When installing the Co2 laser tube 80w 100w 150w for laser machine the two support points of the Co2 laser tube 80w 100w 150w for laser machine should be at a point 1/4 of the total length of the Co2 laser tube 80w 100w 150w for laser machine, leaving enough space between the high voltage end of the Co2 laser tube 80w 100w 150w for laser machine and any other metal surface. If the gap is too small, the high voltage used to trigger the Co2 laser tube 80w 100w 150w for laser machine will spark with the metal surface, which will cause damage to the Co2 laser tube 80w 100w 150w for laser machine and even damage other major electronic components of the laser machine.5. It is recommended that the user add an automatic detection device to the Co2 laser tube 80w 100w 150w for laser machine cooling water circulation system to prevent the Co2 laser tube 80w 100w 150w for laser machine from overheating due to overheating. For details, please consult the laser manufacturer.
