Wavelength Types

Different wavelengths of light produced by each laser marker create different types of marks such as engraving, discoloration, or cutting. Therefore, it is important to match the desired type of mark with the appropriate laser marker.

CO2 Laser Marker
10.6 μm wavelength :
Often used for marking paper, plastic, glass, and ceramic.
The 10.6 μm wavelength is absorbed by transparent materials, so it is often used for applications such as marking films. The development of high-powered models has made it possible to perform functions such as gate cutting of molded parts and PET sheet cutting.
YVO4 Laser Marker
1.06 μm wavelength :
Often used for marking metal, plastic, and ceramic.
Ideal for discoloring plastic and producing high-visibility printing. Up until now, YAG laser markers were selected for applications requiring high power and YVO4 laser markers for applications requiring miniature printing at low power. However, the advent of high-powered YVO4 laser markers has allowed them to take over applications that were once the domain of YAG lasers.
YAG Laser Marker
Fiber Laser Marker
1.03-2.1 μm wavelength :
Often used for marking metal, plastic and ceramic.
Fiber laser markers allow for printing with high power and extremely fast scan speeds while condensing the size of the marking unit. With wavelengths produced in the general range of YAG and YVO4 lasers, Fiber lasers are able to maintain marking quality and save on installation space.
