CO2 Laser Tube
Brand:Startnow
Applied to:
①Laser engraving:Used for fine carving on non-metallic materials such as wood, plastic, glass, leather, etc., widely used in handicraft production, personalized gifts, decorations, and other fields.
②Laser marking:Permanently mark the surface of various materials, such as production date, serial number, QR code, etc., applied to food packaging, electronic components, pharmaceutical packaging, etc.
③Small cutting:Used for cutting thinner non-metallic materials, such as paper, fabric, thin plastic, etc., commonly used in model making, clothing processing, advertising design, etc.
CO2 Laser Tube Is a Widely Used Light Source In Fields Such As Laser Cutting, Laser Marking, And Laser Engraving. It Uses Carbon Dioxide Gas As The Gain Medium And Generates Laser Through High Voltage Excitation.
CO2 laser tubes have the following characteristics
Wavelength:The wavelength of CO2 laser is usually around 10.6 microns, which belongs to the infrared range. This makes it have good cutting and carving effects on many materials, such as non-metallic materials, plastics, wood, glass, etc.
Power:The power range of CO2 laser tubes is wide, ranging from a few watts to several thousand watts, suitable for different application scenarios. High power CO2 lasers can be used for industrial cutting and welding, while low-power lasers are often used for marking and engraving.
Efficiency:The electro-optical conversion efficiency of CO2 lasers is relatively high, generally around 10-20%. Although this is already considered relatively high in lasers, there is still a large amount of heat that needs to be dissipated.
Cooling method:Due to the large amount of heat generated by CO2 laser tubes during operation, an effective cooling system is required. Common cooling methods include air cooling and water cooling, among which water cooling is more common and suitable for high-power lasers.
Lifetime:The lifespan of CO2 laser tubes is usually between 2000 and 10000 hours, depending on the frequency of use, cooling effect, and the quality of the laser.
CO2 laser tube disassembly, replacement, and installation steps
Step 1: Preparation work
①Turn off power:Ensure that the laser machine is turned off and unplug the power plug to ensure complete power outage.
②Wearing protective equipment:Wear protective gloves and goggles to protect yourself from potential harm.
Step 2: Disassemble the old CO2 laser tube
①Disconnect the cooling system:Disconnect the laser tube from the cooling system and be careful not to let coolant spill out. If necessary, containers can be used to collect the coolant that flows out.
②Dismantling cables:Disconnect the high-voltage cable connections at both ends of the laser tube, usually with a high-voltage connector and a ground wire connector. Be careful when operating to avoid damaging the cable.
③Release the fixing clip:Use a screwdriver to loosen the fixtures or brackets that secure the laser tube, usually located at the ends or middle of the laser tube.
④Remove the laser tube:Carefully remove the laser tube to avoid collision or dropping. The laser tube is usually made of glass, which is relatively fragile.
Step 3: Install a new CO2 laser tube
①Check the new laser tube:Check if the new laser tube is intact and undamaged, ensuring that there are no cracks or other damages.
②Installing the laser tube:Place the new laser tube in its original position and carefully secure it to the fixture or bracket. Ensure that the laser tube is placed stably and will not move.
③Connecting cables:Reconnect the high-voltage cable and ground wire to ensure they are securely connected. Be careful not to apply too much force when connecting to avoid damaging the joint.
④Connecting the cooling system:Reconnect the cooling pipes to ensure there is no water leakage. Inject appropriate coolant according to the requirements of the cooling system
Step 4: Testing and Adjusting
①Power on test:Restore power and turn on the laser machine. Carefully check if the laser tube and cooling system are working properly.
②Adjust the optical path:If necessary, adjust the laser's optical path to ensure the output accuracy and quality of the laser beam. Adjustments can be made using targets or calibration tools.
③Security check:Confirm that all connections are secure and there are no leaks or loose cables.
Precautions for use and maintenance
①Cooling system maintenance:Ensure the normal operation of the cooling system, especially the water cooling system, regularly replace the cooling water to avoid scale and impurities affecting the cooling effect.
②Light path adjustment:Regularly inspect and adjust the laser's optical path to ensure the output quality and accuracy of the beam.
③Cleaning:Keep the laser, reflector, and focusing mirror clean to avoid dust and dirt affecting the laser output power and quality.
④Protective measures:When operating, protective goggles should be worn to avoid laser damage to the eyes, and attention should be paid to avoiding direct laser beam exposure to the skin.
CO2 laser tubes are a very important part of laser technology, and their high efficiency and versatility make them widely used in various industrial fields. By proper use and maintenance, its performance can be fully utilized and its service life can be extended.
