Laser marking can be accomplished with several types of lasers. The most common are gas lasers, solid state lasers, and fiber lasers. Each type works in a unique way to create a laser beam at a particular wavelength. Each wavelength is suitable for marking in specific ways on specific materials.

Laser wavelengths for marking various materials.

Choosing the Right Wavelength for Your Material

Gas Lasers:  CO2 gas lasers are excellent for marking a wide range of plastics and organic materials.

Fiber and Solid State Lasers: The lasers in these categories include Nd:YAG, Nd:YVO4 (Vanadate), and Ytterbium Fiber lasers. They all utilize approximately the same wavelength of laser beam, which is particularly good for marking metal surfaces as well as plastics.
