Difference Between Fiber Laser Marking Machine And CO2 Laser Marking Machine

The difference between fiber laser markingmachine and carbon dioxide laser marking machine is mainly the workingprinciple, advantages and application industry of laser.

Fiber laser refers to the laser source thatuses rare-earth-doped glass fiber as the gain medium. The working principle offiber laser is that it is easy to form high power density in the fiber underthe action of pump light, which causes the laser energy level of the workingsubstance of the laser to “particle number inversion ”, When a positivefeedback loop (forming a resonant cavity) is properly added, a laser oscillationoutput can be formed, and a laser beam with a wavelength of 1064 nm isgenerated.

Advantages of fiber lasers:

1. The manufacturing cost of glass fiber islow, the technology is mature, and the life is up to 100,000 hours;
2. Fiber laser is smaller and moreintegrated;
3. No adjustment, no maintenance, highstability;
4. Fiber lasers are qualified for harshworking environments and have a high tolerance for dust, vibration, shock,humidity, and temperature;
5. No need for thermoelectric cooling andwater cooling, just simple air cooling can greatly reduce costs;
6. High electro-optical efficiency: Thecomprehensive electro-optical efficiency is over 25%, which can greatly savepower consumption during work and save costs.

Application scope of fiber laser markingmachine: all kinds of metals and some non-metals, electronic separationcomponents, integrated circuits (IC), electrical circuits, mobile phonecommunications, hardware products, cutlery and kitchenware, tool accessories,precision instruments, glasses and watches, computers Keyboards, jewelry, autoparts, plastic buttons, plumbing fittings, sanitary ware, PVC pipes, medicalequipment, packaging bottles, etc.

The working principle of a CO2 RF tubelaser is to excite a mixed gas of CO2, neon, argon, etc. through an excitationsource, and then through particle number inversion and light amplification tofinally generate a laser with a wavelength of 10.64um.

CO2 laser advantages:

1. The life of CO2 laser is up to 30,000hours for one charge, and it can be used for inflation.
2. Cooling method: air cooling, stablelong-term operation
3. The spot pattern is close to TEM00, thespot is round and uniform, and the spot diameter is small
4. Low voltage power supply, high safety

CO2 laser marking machine applications:clothing accessories, pharmaceutical packaging, alcohol packaging, buildingceramics, beverage packaging, fabric cutting, rubber products, casingnameplates, craft gifts, electronic components, leather and other industries.

Compared:

1. The service life of the fiber lasermarking machine is 100,000 hours, and the co2 marking machine is 30,000 hours.The former is much longer than the latter.
2. In terms of accuracy, fiber lasers arenano-level processing methods, while CO2 lasers are micron-level. The accuracyof fiber lasers is higher than that of CO2 lasers.
3. The application range of fiber lasermarking machine is different from that of co2 laser marking machine. Fiberoptic marking machine is more widely used than CO2 marking machine. But bothhave irreplaceable aspects.
