CO₂ laser cutting machine of working principle
CO₂ laser cutting employs gas discharge excitation and 10.6μm infrared thermal processing through three physical phases:
1. Laser Generation & Transmission
- Gas Excitation: High-voltage current ionizes CO₂/N₂/He mixture, inducing molecular vibrational transitions to emit 10.6μm photons
- Resonant Amplification: Photons oscillate within resonator cavity (HR mirror + output coupler), forming high-energy CW/pulsed beam
- Beam Delivery: Guided by copper mirrors, collimated via beam expander, then focused by cutting head (spot size depends on lens curvature)
2. Material Interaction
Non-Metals (e.g., Acrylic):
- Laser absorption → Instantaneous vaporization (~400°C for acrylic) → Molten debris blown away by assist gas (air/N₂)
- Edge Quality Control: Power density <10⁶W/cm² minimizes carbonization (achieving Ra<0.8μm polished edges)
Metals (Requiring Coating):
- Laser-induced oxidation (Fe+O₂→FeO) → Exothermic reaction enhanced by O₂ → Slag ejected by high-pressure gas (15-20Bar)
3. Dynamic Control
- Real-time Focus: Capacitive sensor maintains 0.5-2mm nozzle-to-workpiece distance
- Power Modulation: 1-5kHz pulse frequency prevents thermal damage to thin materials (e.g., 0.5mm wood)

1. Non-Metal Specialization:
- 3-5× faster than fiber lasers on acrylic/wood/textiles
2. Mirror-Finish Edges:
