Abstract

Generally, the beam distribution in the tissue in interaction with a pulsed laser is defined by the optical properties (effective scattering and absorption coefficient). A special Er:YAG device used for blood sampling without any pain is presented. Our device emitting on 2940 nm has a special function. It can give four energy levels for four types of skin. At 3000 nm there is an absorption peak in water, and the absorption in tissue is intense and the vaporization is immediate and superficial without surrounding damages. Additionally, the very short duration of the pulse (a few hundred microseconds) avoids the phenomenon of thermal diffusion.
