Principle of CO? Laser Marking Machine

The CO2 laser is a gas laser that produces a wavelength of 10.6 μm, which falls within the mid-infrared frequency band. CO2 lasers offer relatively high power and high electro-optical conversion efficiency, making them one of the most powerful types of lasers available. The CO2 laser uses CO2 gas as the working medium. CO? and other auxiliary gases are filled into the discharge tube. When a high voltage is applied to the electrodes, a glow discharge is generated in the discharge tube, causing the gas molecules to release laser light. The released laser energy is then amplified for laser processing.

Advantages of CO? Laser Marking Machine
With a wavelength of 10.64 μm, it is easily absorbed by most non-metallic materials. It features high electro-optical conversion efficiency, and the laser output is primarily in the fundamental mode, ensuring good and stable beam quality. It enables non-contact processing with no mechanical wear or deformation, requires no consumables, offers low processing costs and high processing efficiency, and operates at speeds measured in milliseconds. It provides flexible control, is compatible with automated production lines, allows fast marking with easy customization of logos, and requires no molds.

Applications of CO? Laser Marking Machine:

The CO2 laser marking machine offers high engraving precision, fast speed, and stable performance. It can quickly engrave intricate patterns on non-metallic materials with clear, wear-resistant marks. The engraving depth can be adjusted freely, and no consumables are required during the process. It is widely used in industries such as eyewear, buttons, leather, fabrics, ceramics, glass, crystal, rubber, bamboo, and wood products.
