CO₂ Laser Working Principle
co2 laser markers use a lasing medium composed of carbon dioxide, nitrogen, hydrogen, and helium.they produce invisible lasers in the far infrared light spectrum range,which makes them ideal for marking organic，materials, including wood,paper, resins,rubber, and transparent materials like glass and pet.
What is a CO₂ Laser?
CO2 laser marking systems utilize a sealed carbon dioxide gas mixture as the active laser medium (emitting at a 10.6 µm wavelength). When excited by high-voltage electrical energy, gas molecules release an intense far-infrared laser beam.
When the 10.6 µm laser beam impacts non-metallic substrates, the surface material rapidly absorbs thermal energy, triggering precise physical and chemical reactions:
Working Principle: The 4-Step Fusion Process
01
Vaporization & Etching
On acrylic, paper, and glass, the intense thermal energy instantly vaporizes surface material layers or induces controlled micro-fracturing. This process yields smooth, frosted, or precise vector markings without affecting structural integrity.
02
Thermal Carbonization
On organic substrates like wood, bamboo, and leather, the laser triggers localized micro-combustion. This controlled heat reaction causes natural dark carbonization, producing sharp, permanent, high-contrast text and graphic patterns.
03
Color-Change Marking
On coated surfaces, painted metals, and specific polymers, laser energy selectively strips the top layer or alters the molecular dye structure. This exposes the underlying substrate tone to achieve high-visibility contrast without deep engraving.
04
Plastic Foaming & Melting
On engineering plastics, dark PVC, and synthetic rubber, localized heat creates microscopic gas bubbles within the surface polymer. This produces raised, tactile, and highly legible alphanumeric codes or serial numbers.

FAQ
Frequently Asked Questions about CO₂ Laser Marking Machines
Q:What is the difference between Glass Tube (DC) and Metal Tube (RF) CO2 lasers?
Glass tubes (DC) offer high peak power at an entry-level cost, making them ideal for budget-conscious buyers focused on basic marking and thick cutting. RF metal tubes deliver superior beam quality, finer spot sizes, faster pulse frequencies, and an exceptionally long operational lifespan (20,000+ hours) with low power attenuation.
Q: Can a CO2 laser mark directly on metal surfaces?
Standard CO2 lasers (10.6 µm) are primarily designed for non-metal and organic substrates. They cannot directly etch bare metals. However, they can effectively mark anodized aluminum, painted metal sheets, or coated metal surfaces by cleanly removing the top oxide or paint layer.
Q: Can a CO2 laser mark on large-format workpieces?
Yes! For workpieces exceeding single field lens limits (e.g., larger than 300×300 mm), our CO2 laser systems integrate seamlessly with Extended Horizontal Translation Tables or motorized XY-Axis Translation Stages to perform automatic tiled marking across broad surfaces.
Q: Do you offer OEM/ODM customization for specific production line needs?
Absolutely. We provide tailored OEM/ODM solutions to match your factory workflow. Options include customized machine enclosures, specialized optical wavelengths (e.g., 9.3 µm for thin PET film), integrated photoelectric sensors for automated conveyor lines, custom software plugins, and customized corporate branding/casing colors.
Q: What daily maintenance is required for a CO2 laser machine?
Maintenance is straightforward and cost-effective with zero ink consumables. Daily routine care involves keeping the field lens and galvo optical mirrors clean using isopropyl alcohol wipes, removing dust from the fume exhaust outlet, and ensuring proper cooling water or air circulation. A quick 5-minute check per week ensures optimal processing performance.
Q：What after-sales service and technical support are included after purchase?
All CO₂ laser machines come with a complete after-sales system, including free pre-delivery debugging, lifelong remote software guidance, 24/7 online technical support. We provide free software upgrades, operation tutorials and maintenance guides to ensure stable long-term operation of customer equipment.
