Working Principles of Laser Marking Machines

Laser marking machines work based on the principle of using high-energy laser beams to mark the surface of various materials. The specific working principles differ among different types of lasers, which are mainly determined by the lasing medium used.

Fiber Laser Marking Machines

Fiber laser marking machines utilize a fiber laser as the lasing medium. The laser beam is generated within an optical fiber and is then amplified. The amplified beam is directed towards the marking surface through a scanner system, creating the desired marking.

CO2 Laser Marking Machines

CO2 laser marking machines use a carbon dioxide gas mixture to produce the required laser beam. The CO2 laser is excited electrically and produces a wavelength of 10.6 micrometers. This wavelength is suitable for marking a wide range of organic materials.

UV Laser Marking Machines

UV laser marking machines employ an ultraviolet laser beam for marking surfaces. The UV laser has a short wavelength, typically around 355 nanometers, which enables precise marking on sensitive materials like plastics and glass.
