CO2 Laser Beam—Biological Tissue Interaction with Reference to Ablation
J-F. Coutouly, P. Deprez, F. Breaban and J-P. Longuemard

Laser ablation of biological materials (human or animal tissues) is of definite interest. For example companies working in the food-processing industry wish to cut or clean animal material in conditions of optimum hygiene. In this area, lasers can an extremely interesting alternative. This paper first of all describes a theoretical study of the interaction between a laser beam and biological material applied to ablation, and then an experimental validation of the possibility of ablating animal or human tissue.

Keywords: Laser interaction, pulsed CO2 laser, biological materials, ablation.
