Which dental laser type has the longest wavelengths?

The CO2 laser is distinguished by having the longest wavelengths compared to other types of dental lasers listed. It operates typically at a wavelength of around 10,600 nanometers, which positions it well into the infrared spectrum. This longer wavelength allows CO2 lasers to be particularly effective for soft tissue procedures in dentistry, as they are absorbed well by water and organic tissues.

This absorption characteristics make CO2 lasers ideal for processes such as cutting, coagulating, and vaporizing soft tissues, while minimizing damage to surrounding areas due to their focused energy delivery. Furthermore, their efficacy in delivering high-power energy and cutting through tissue makes them a preferred choice in various soft tissue surgical applications in dental practice.

The other laser types mentioned have shorter wavelengths, which affect their interactions with tissues differently and are typically used for more specific applications, such as hard tissue cutting or particular soft tissue treatments.
