Laser-tissue interactions

Abstract

1.Light represents one portion of a broader electromagnetic spectrum. 2.Light-tissue interactions involve the complex topics of tissue optics, absorption, heat generation, and heat diffusion 3.Lasers are a special type of light with the characteristics of monochromaticity, directionality, and coherence. 4.Coagulation/denaturation is time and temperature dependent 5.Proper selection of light parameters is based on the color, size, and geometry of the target 6.Wound healing is the final but not least important part of the laser tissue sequence (the epilogue) 7.Laser-tissue interactions are fluid - the operator should closely examine the skin surface during all aspects of the procedure 8.Pulse duration and light doses are often as important as wavelength in predicting tissue responses to laser to irradiation
