What is the wavelength of YAG laser?

The wavelength of the YAG laser is 1064 nm, which is significant for various applications, particularly in medical and cosmetic procedures. This wavelength is in the infrared range, making it highly effective for targeting deeper skin structures and tissues. The 1064 nm wavelength is absorbed by melanin and can penetrate the skin more deeply than shorter wavelengths, allowing for effective treatments of hair removal, vascular lesions, and certain types of tattoos.

In comparison to the other options, 532 nm is typically associated with frequency-doubled Nd:YAG lasers used for specific applications such as treating superficial pigmented lesions, while 755 nm is the wavelength of the Alexandrite laser, known for its effectiveness on lighter skin types. The 980 nm wavelength is often used in diode lasers, which target both hair follicles and vascular structures, but it does not belong to the YAG laser category. Understanding these distinctions highlights the importance of the specific wavelength in determining the effectiveness of laser treatments in various clinical scenarios.
