The advent of laser markers has led to the rapid development of modern marking technology. With their high precision, high speed and flexibility, these laser devices have quickly become popular and their market share has gradually increased. Currently, CO2, fiber and UV laser markers are the three most common types. In this article, we will briefly analyze the advantages and limitations of these three portable laser markers.according to mini fiber laser marking machine Industry veterans said that its development will still be in a good situation. https://riselaser.net/product/rl-20eb-mini-fiber-laser-marking-machine
CO2 laser marker
The CO2 laser marker is the most widely used laser marker. Its name comes from the mixed gas in the laser tube, which is mainly composed of carbon dioxide, nitrogen and helium. The device achieves marking by emitting a laser beam with a wavelength of 10.6 microns and heating the material to a vaporized state. The marking accuracy is very high, and it can even cut fine parts as small as 0.1 mm. It is widely used in the processing of various non-metallic materials.
CO2 laser marking machines are widely used in many industries such as woodworking, packaging, textiles, automobiles, electronic equipment manufacturing, and handicraft processing. Although their marking speed is slightly slower than the other two and requires regular maintenance, their low cost makes them the mainstream choice in the market. In addition, CO2 laser marking machines are also popular for their flexible installation, small footprint, and easy adaptation to various working environments.
Fiber laser marking machines
Fiber laser marking machines have been available since the 1990s. They use glass optical fibers doped with rare earth elements as core materials. Pump light provides energy to form high energy density inside the optical fiber, so that particles reach the ＾inversion state￣ to produce lasers, which can be amplified and output through the feedback loop (resonant cavity). Compared with CO2 laser marking machines, fiber lasers have shorter wavelengths (about one-tenth of their wavelength), so they are suitable for finer engraving, especially on metal and plastic surfaces.
Fiber laser marking machines are favored in the automotive, aerospace, electronics, and metal processing fields for their high precision and reliability. Although more expensive than CO2 lasers, fiber lasers last longer and require little maintenance, making them a long-term investment.
UV Laser Marking Machine
UV lasers are similar to fiber lasers, but use UV solid-state drives. They have a wavelength that is only one-third that of fiber lasers, making them more precise. In addition to being able to engrave similar materials to fiber lasers, UV lasers excel at processing certain organic materials, such as wood. They use a technique called ＾cold processing￣ that effectively reduces heat generation and greatly reduces the risk of material deformation.
UV lasers are widely used in demanding fields such as electronics, aerospace, and medical due to their unique characteristics. Due to the newer technology, UV lasers are generally the most expensive of the three lasers. In addition, there are fewer power options for UV lasers on the market today, with only 3-watt, 5-watt, and 10-watt models available.
CO2, fiber, and UV lasers are all excellent tools for achieving high-quality marking on a variety of materials. They each have advantages and limitations and are suitable for different customer needs. CO2 lasers are popular because of their affordability, while fiber and UV lasers are worth investing in growth industries.
