Which type of laser uses a 1064 nm wavelength?

The Nd:YAG (Neodymium-doped Yttrium Aluminum Garnet) laser is known for its 1064 nm wavelength, which falls in the near-infrared spectrum. This wavelength is particularly significant in various medical and aesthetic applications, such as hair removal, tattoo removal, and treatment of vascular lesions. The 1064 nm wavelength allows for deeper penetration into the skin while minimizing damage to the surrounding tissues, making it effective for a range of skin types.

In contrast, the other types of lasers listed each operate at different wavelengths, contributing to their specific uses and effects. For instance, diode lasers typically operate at wavelengths ranging from 800 nm to 950 nm, while ruby lasers emit a wavelength of 694 nm, and Alexandrite lasers operate at around 755 nm. These differences in wavelength influence the absorption characteristics and interaction with various chromophores in the skin, which is why understanding the specific wavelength of each laser type is crucial for their application in clinical settings.
