What wavelength of light is typically used for tattoo removal with Q-switched lasers?

• A. 532 nm and 1064 nm
• B. 400 nm and 450 nm
• C. 800 nm and 940 nm
• D. 600 nm and 750 nm

Answer: (A)

The typical wavelengths used for tattoo removal with Q-switched lasers are 532 nm and 1064 nm. These specific wavelengths are effective due to their ability to target different ink pigments present in tattoos. The 532 nm wavelength is well-suited for removing green and yellow inks, as these colors absorb light effectively at this wavelength. On the other hand, the 1064 nm wavelength is effective for darker inks, particularly black and blue, because it penetrates deeper into the skin and can effectively break down larger ink particles that are more difficult to remove. Overall, the combination of these two wavelengths allows for a broader range of tattoo ink colors to be effectively treated, which is why they are commonly used in Q-switched laser systems for tattoo removal. The other options contain wavelengths that are not as effective for this specific application, as they either target other skin conditions or are less optimal for the broad spectrum of tattoo pigments.
