Abstract: From the plane semi-limitless one-dimensional active heat diffusion equation and biochemical reaction rate equation, the maximum dosage of defocusing CO2 laser irradiation for skin tissue are derived. The relationships between the laser dosage, temperature increasing and biochemical reaction rate are analyzed. Finally,the mechanism of CO2 laser temperature effects on open-wound skin tissue is discussed.
