title: [Removal of tattoos with the Nd:YAG laser].
abstract: Irradiation of 20 tattoos using the Q-switched Nd:YAG laser (energy density 3-5 J/cm2, asymmetrical pulse shape with 50% energy output in 18 ns, spot size 3 mm in diameter) gave the impression that black ink tattoos can be completely removed without scarring. Some patients needed several treatments. The results continued to improve even some months after the irradiation. In preliminary experiments on excised tattooed and untattooed skin the non-Q-switched Nd:YAG laser had distinct burning effects. It was therefore not tested in patients. The results of chemical, physical, and histological examinations are discussed with special reference to toxic side-effects that might be induced by laser irradiation.
