Abstract

A light-triggered tattoo process. A strong absorber of light energy and tattoo material are sandwiched under pressure between a skin region and a transparent window. Short pulses of light, at frequencies strongly absorbed by the strong absorber, illuminates the strong absorber through the window creating micro-explosions in the strong absorber that drive particles of the tattoo material into the skin region producing a tattoo.
