What wavelength does the Nd:YAG laser operate at within the invisible light spectrum?

The Nd:YAG laser operates at a wavelength of 1064 nanometers, which places it in the infrared region of the spectrum, making it invisible to the human eye. This wavelength is particularly significant in various applications, including laser surgery and hair removal, due to its deep penetration capabilities into the skin.

At this wavelength, the energy of the laser light can be effectively absorbed by certain chromophores in the skin, such as melanin and hemoglobin, which allows for targeted treatment of hair follicles and vascular lesions without damaging the surrounding tissue. The unique properties of the Nd:YAG laser have made it a popular choice in the field of aesthetic treatments, as it balances the need for effective energy delivery with the safety of the surrounding structures.

The other wavelengths listed, such as 532 nm, 800 nm, and 980 nm, correspond to different lasers or applications and do not represent the operating wavelength of the Nd:YAG laser. Understanding the specific capabilities of the Nd:YAG laser enhances its effective use in medical and cosmetic procedures.
