Carbon Dioxide (CO2) Lasers (45 companies)
Carbon dioxide (CO₂) lasers use the energy-state transitions between vibrational and rotational states of CO₂ molecules to emit at long IR, about 10 µm, wavelengths. These lasers can maintain continuous and very high levels of power and are typically used in cutting, welding, etching, and marking applications.
