What is a CO2 Laser and How Does It Work?

A CO2 laser is a gas laser that uses a carbon dioxide gas mixture to generate an infrared laser beam at 10.6 µm. It is one of the most widely used lasers in industrial and commercial engraving and cutting due to its high efficiency and versatility.

Compared with other laser types, the CO2 laser is ideal for non-metal materials such as:

  • Wood

  • Acrylic

  • Leather

  • Fabric

  • Paper

  • Glass

  • Plastics (non-metal)

Why Choose a CO2 Laser Engraver for Your Business?

A CO2 laser engraver is the go-to machine for cutting and engraving non-metals with excellent speed and accuracy. Whether you’re producing signage, packaging, model-making, or art & crafts, a CO2 laser engraver offers:

  • High-speed engraving

  • Smooth, clean cuts

  • Large working area

  • Long service life

  • Low maintenance cost

If you’re looking for the best CO2 laser to start or scale your engraving business, our machines offer unmatched performance at a competitive price.

What Is a CO2 Galvo Laser?

Unlike standard flatbed engravers, a CO2 galvo laser uses a galvo scanning system to steer the laser beam with precision mirrors. This enables ultra-fast, non-contact marking ideal for:

  • Batch marking on leather, wood, plastics

  • High-speed barcodes and serial numbers

  • Label-free packaging

  • Flexible manufacturing lines

The CO2 galvo laser combines the speed of galvo technology with the power of CO2 lasers—making it one of the best CO2 laser solutions for industrial-grade precision marking.

Frequently Asked Questions (FAQ)

Q1: What’s the difference between a CO2 galvo laser and a flatbed CO2 laser?
A CO2 galvo laser uses high-speed mirrors for beam deflection, making it ideal for fast marking, while flatbed CO2 laser engravers use gantry motion systems for precise cutting and large-area engraving.

Q2: Can CO2 lasers engrave metal?
Standard CO2 lasers cannot engrave bare metal. However, they can mark coated metals or anodized surfaces. For metal engraving, consider a fiber laser system.

Q3: What’s the best CO2 laser power for engraving?
For engraving tasks, 30W to 60W CO2 laser engravers are ideal. For cutting thicker materials, 80W or above is recommended.

Q4: How long does a CO2 laser tube last?
Typically, a CO2 glass laser tube lasts between 3,000 to 10,000 hours depending on usage and cooling.

Q5: Do you provide OEM service?
Yes, we offer OEM/ODM service, including customized branding, machine configuration, and software.
