Heat condition and destruction of tissue under the action of Nd:YAG laser

摘要

In this paper the physics processes proceeded in the tissue under laser radiation action are described. From heat and mass transfer analysis the tissue destruction model is received as a many boundaries Stefan problem with sudden change of thermophysical parameters on phase boundaries. A numerical solution of the 1-D problem is presented for model testing. It permits us to define a size of carbon zone and a boundary movement velocity. The resulting analysis shows that the model satisfies the real process of the tissue destruction.
