WebThe laser wavelength can be tuned by altering the isotopic ratio of the carbon and oxygen atoms comprising the CO 2 molecules in the discharge tube. Construction [ edit] Because CO 2 lasers operate in the infrared, special materials are necessary for their construction. WebNon-ionizing radiation includes the spectrum of ultraviolet (UV), visible light, infrared (IR), microwave (MW), radio frequency (RF), and extremely low frequency (ELF). Lasers commonly operate in the UV, visible, and IR frequencies. Non-ionizing radiation is found in a wide range of occupational settings and can pose a considerable health risk ...
