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
Q1: What is the difference between Glass Tube (DC) and Metal Tube (RF) CO₂ lasers?
A: Glass DC tubes provide a cost-effective solution for general marking, engraving, and cutting applications. RF metal tubes typically offer a finer beam, smaller focused spot, faster pulse response, and better stability for precision marking and high-speed production. The most suitable source depends on your material, required marking quality, production speed, and budget.
Q2: Can a CO2 laser mark directly on metal surfaces?
A: Standard 10.6 μm CO₂ lasers are primarily designed for non-metallic materials such as wood, leather, paper, acrylic, rubber, and many plastics. They are generally not suitable for direct engraving on bare metals. However, CO₂ lasers can process certain coated, painted, anodized, or specially treated metal surfaces by removing or modifying the surface layer. For direct marking on bare metal, a fiber laser is usually the more suitable choice.
Q3: Can a CO₂ laser mark large-format workpieces?
A: Yes. For workpieces larger than the standard marking field, the system can be configured with an extended translation table or motorized XY positioning stage. This allows the workpiece to be repositioned or processed in multiple marking areas, depending on the required size, artwork, and automation setup.
Q4: Do you offer OEM/ODM customization for specific production line needs?
A: Yes. We provide OEM/ODM configuration options for different production requirements, including machine enclosures, laser source and wavelength selection, marking areas, rotary systems, positioning stages, conveyor integration, sensors, control interfaces, branding, and other application-specific configurations. Our engineering team can recommend a system based on your material, marking process, and production workflow.
Q5: What daily maintenance is required for a CO₂ laser marking machine?
A: Routine maintenance is relatively simple. Keep the work area, optical path, ventilation system, and cooling system clean and operating normally. Optical components should be inspected periodically and cleaned only according to the manufacturer’s recommended procedure. For water-cooled configurations, cooling water and chiller condition should also be checked regularly. Maintenance requirements may vary between RF and DC tube systems.
Q6: What after-sales service and technical support are included after purchase?
A: We provide remote technical support for machine setup, software configuration, parameter adjustment, operation guidance, troubleshooting, and routine maintenance. Operation manuals and training materials are supplied with the machine, and replacement parts and technical assistance are available when required. Support arrangements can also be confirmed according to the machine configuration and destination market.
