CO2 Laser (3000W) Fiber Laser (3000W)
Laser System Laser based on a gas mixture in which light is amplified by carbon dioxide molecules. Diode Pumped Laser with a doped fiber as gain medium where most of the laser module is made of fiber
Reflectivity CO2 lasers are less effective for cutting highly reflective materials, since much of the beam is reflected back towards the source and not absorbed by the substrate. As a result, higher power levels are required for cutting as compared to fiber lasers. Much less power is required for cutting reflective materials like aluminum or copper since more of the laser energy is absorbed by the substrate. This allows for intricate high quality cutting at higher efficiencies than comparable laser cutting systems.
