Sub-Nano Pulsed Laser Transport through Different Skin Types for Tattoo Removal Application

In this study, a thin scattering tissue layer model developed using modified Monte Carlo method [1] was used as skin model to simulate African American, Asian, and Caucasian skins and different laser transport trends were found for different skin types while running picosecond pulsed laser through the skin model. The optical properties of this skin types were simulated using their optical coefficients (i.e. absorption coefficient) found from the existing literature. The study of laser transport through different skin types and finding associated trends are significant for tattoo removal application in order to optimize the wavelength and pulse width of the laser from different skin types.
