| Abstract [eng] |
The aim of this work was to investigate the bleaching of tattoos embedded in modular systems with femtosecond pulses. The tattoos were exposed to laser radiation at a fluence of 〖13 mJ/cm〗^2 and 〖1 mJ/cm〗^2 and the effect was recorded by the photo-acoustic absorption method. Examples of red dye and laser dye were dried and analyzed by FT infrared spectroscopy using a surface-reflection additive ATR and FTIR Perkin Elmer spectrometer. In addition, the absorption spectra of the aqueous paint solutions were measured before and after the laser exposure and after the microscope image samples immediately after the interaction with the radiation. |
