What is the wavelength of a Co2 laser?

The correct choice identifies the wavelength of a CO2 laser, which is 10,600 nanometers (nm). This specific wavelength falls within the infrared spectrum and is particularly effective for various medical and aesthetic applications, including surgical procedures and skin resurfacing, as it is well absorbed by water and tissue.

The significance of this wavelength lies in its ability to target tissues with high water content, making it especially useful for cutting, ablating, and vaporizing tissue during medical procedures. Because of its length, this wavelength allows for deep penetration into the skin without significant thermal damage to the surrounding tissues, enabling precise and controlled treatments.

Other wavelengths mentioned, such as 800 nm, 532 nm, and 1,064 nm, correspond to different types of lasers. These lasers cater to specific applications based on the absorption properties of the target tissues or pigments in the skin. However, they do not represent the characteristics of a CO2 laser, which is distinctly associated with the 10,600 nm wavelength. This understanding is essential for practitioners in the field of medical aesthetics when determining the appropriate laser for a given treatment.
