What is a fiber laser?
A fiber laser is a type of solid-state laser that uses an optical fiber—doped with rare-earth elements such as ytterbium—as its gain medium. It is a newer and more advanced technology, especially well-suited for metal marking and cutting.
What is a CO2 laser?
A CO2 laser is a type of gas laser that uses a carbon dioxide gas mixture as its active medium. This type of laser has been widely used since the 1960s and is known for its reliability and versatility, particularly when working with non-metal materials.
How A Fiber Laser Works:
Fiber lasers generate a laser beam using a solid-state laser diode. The beam is then channeled and amplified through a specialized fiber optic cable doped with rare-earth ions. The result is a highly focused, intense beam of near-infrared light (typically at a wavelength of 1064 nanometers). This beam can be directed through a lens system for engraving, cutting, or marking surfaces.
How a CO2 Laser Works:
CO2 lasers produce light by electrically exciting a mixture of gases—primarily carbon dioxide (CO2), nitrogen, and helium—inside a sealed tube. The electrical energy excites the gas molecules, causing them to emit a beam of infrared light at a wavelength of 10.6 micrometers. Mirrors and lenses are used to direct and focus this beam onto the material being cut or engraved.
Why choose a fiber laser?
Perfect for Metal Marking: Easily marks stainless steel, aluminum, brass, copper, and other metals—even hard-to-mark alloys.
Fast and Efficient: GT SCHMIDT’s fiber lasers offer faster marking speeds and lower power consumption than CO2 alternatives.
Why choose a CO2 laser?
Versatility for Non-Metals: Ideal for marking or engraving packaging, signage, and organic materials.
Capable of marking transparent materials: including clear acrylic, glass, and some plastics.
