| Abstract | ||
| The paper describes the design and performance analysis of pigmentation removal using a Q-switched lasers ( Nd:YAG 1064nm and frequency doubling source of 532 nm ) at fluence(2-12.7J/cm2) used to remove (black, blue, and green) and (red) pigment respectively, for different skin types(I-IV). All parameters calculated and selected by using a model for a laser system simulated and practically(clinically ) by using IPL Q-switched laser source depending on skin color and tattoo specifications to satisfy the number of lesions. Visual observation and histological analysis of biopsies performed to evaluate the results of relation among spot sizes, laser intensity and skin parameters for several treatments. The behavior of the Nd:YAG 1.064 nm was the safer to use clinically in real cases to get minimal adverse reactions and complications . | ||
