Paper Abstract

Clinical application shows that the Q-switched laser therapy on pigmented lesions based on the principle of selective thermolysis is good in efficiency. But the mechanism of this method of treatment remains unclear yet. Elementary researches are up to date restricted to the levels of morphological observation mainly. The beginning split second process within which laser pulse is interaction with dermal tissues has not been investigated in detail. This process also includes a series of sub processes of super high intensity of photo thermotics, plasma shock wave, super express boil inflation, et. Researches of experimental tests to the momentary processes mentioned above have been performed in this project. The results suggest that laser ablation impact and shock wave induced by laser play important rules in the process.
