What type of laser is typically used for tattoo removal?

The Q-switched laser is typically used for tattoo removal due to its ability to produce short, high-energy pulses that target the ink particles in the skin. This laser works by momentarily storing energy and then releasing it in a very short burst, which allows it to break up the tattoo ink into smaller particles that can be more easily absorbed and eliminated by the body.

The specific wavelengths emitted by Q-switched lasers, such as 532 nm or 1064 nm, are particularly effective on a variety of ink colors, making it a versatile choice for tattoo removal. Its precision minimizes damage to surrounding tissue, contributing to a safer and more effective removal process compared to other laser types.

In contrast, the other laser types mentioned may not provide the same level of effectiveness or safety for tattoo removal. For example, diode lasers are often used for hair removal and may not effectively target tattoo inks. CO2 lasers are commonly used for skin resurfacing rather than ink removal, and Er:YAG lasers also focus on tissue ablation, which is not ideal for breaking down tattoo pigments in a controlled manner like Q-switched lasers do. Therefore, using a Q-switched laser is a well-established and favored method for tattoo removal.
