Laser processing 2of bone is a very complicated task since bone consists of different components with very different physical properties that give bone its combination of flexibility and solidity. While the mineral bone component melts at temperatures above 1280°C, bone cells will already be damaged by minor temperature rises above 42°C. The process model for hard tissue ablation with pulsed IR lasers is the so-called thermo-mechanical ablation.
