Many types of laser engraving machines are available. These engraving machines have different functions and are suitable for a variety of applications. The most common types of laser engraving machines are:
Fiber laser marking machine: A fiber laser marking machine is a laser engraving machine that uses glass fiber to conduct electricity. The laser diode generates light and moves along the fiber optic cable, where it collects energy and changes shape to suit the application. Fiber laser marking machines can be accurately marked and extremely powerful. Learn more about the role of fiber laser marking machines in our blog post.
Crystal lasers: Engraving machines with crystal lasers use garnet or vanadate crystals to change the characteristics of the beam and give it extremely high power. For example, vanadate laser marking machines provide better beam quality and focal depth than fiber laser marking machines.
CO2 Laser Marking machine: This laser engraving machine guides the light emitted through a glass tube containing gases such as carbon dioxide (CO2), helium, nitrogen and hydrogen. As the intensity of these CO2 laser marking increases, the machine reflects light between the two mirrors. CO2 laser marking machine is a multi-functional machine, suitable for materials such as plastic and wood.
Ultraviolet laser marking machines: These laser engraving machines use ultraviolet (UV) light to mark materials through a cold marking method. Manufacturers can cause minimal thermal damage to organic materials and plastics.
