Technical Comparison: CO₂ Lasers vs. Fiber Lasers

Oct. 3, 2025

1. Fundamental Laser Physics

  • CO₂ Lasers
    • Gain Medium: Gas mixture (CO₂, N₂, He).
    • Wavelength: 10.6 μm (far-infrared).
    • Mode of Operation: Excitation via electrical discharge across gas; typically continuous-wave (CW) or pulsed.
    • Photon-Material Interaction: Strong absorption by dielectrics, ceramics, polymers, water-rich tissues; weaker absorption in metals unless surface is pre-treated (e.g., with coatings).
