The Co2 laser is one of the earliest gas lasers. Developed by Kumar Patel in 1964, it is still one of the most useful lasers today. With its high power and levels of control, Co2 lasers can be used for applications requiring precision, mass production, and most importantly, personalization. Co2 laser engravers and cutters are highly precise and can be used to create designs, decorations, and the like on just about any material you can think of, including wood, plastic, metal, and paper to name a few.

In a Co2 laser cutter, light is produced when electricity runs through a gas-filled tube with mirrors at both ends. One mirror is fully reflective while the other one lets some light come through. These mirrors guide the laser beam into the material that is to be cut. The gas is typically a mixture of carbon dioxide, nitrogen, hydrogen, and helium.



The fiber laser uses an optical fiber, somewhat similar to fiber optic lines used in telecommunications, to create and transfer the photons (light). These fiber cables can be very long and provide great flexibility without the use of mirrors to redirect the laser light. The use of a glass-based fiber is a significant advantage over CO2 lasers, since it means that fiber lasers do not rely on perfectly aligned and clean mirrors to enable motion of the nozzle tip. Instead, they are flexible, small, and light.

The cross section of the fiber shows three layers, each with specific characteristics of light refractivity. The outer layer has a special cladding with the lowest refractive index. The middle layer has a higher refractive index compared to the outer cladding, and its’ goal is to initiate the work of the laser as well as guarantee optimal transmission of the pumping energy. The center layer is the active optical core and is doped with rare earth elements, in this case Yb (Ytterbium). It has the highest refractive index of all three layers.



CO2 Galvo laser machine is used for engraving, marking and cutting of technical textiles, clothing, leather, shoes, automotive, carpets, sandpaper, paper cards, advertising and other industries.

Equipped with CO2 RF metal laser source and high-tech Galvanometric head, using three-axis dynamic focusing galvanometer processing technology, Goldenlaser’s Galvo laser system is the industry leader in technology level.

Our Galvo laser system is designed for laser processing with fine spot size, large working range and high flexibility. It has the features of high precision and unparalleled speed compared to a gantry laser system (X-Y axis laser plotter).



Metal laser tubes use radio frequency to fire a fast pulsing laser with quick repeatability. They perform the engraving process with ultra-fine detail as they have a smaller laser spot size. They have a longer life span of 20000 hours, before the need for the refurbishing of gas arises.
