Abstract :
Adaptive control is proposed as a useful process for an improvement of Nd:YAG laser treatments. A computer-controlled Nd:YAG laser system with a closed-loop capability has been developed. Infrared radiometry provided noncontact temperature measurement for real-time coagulation and ablation control. The controller design is based on the predicted response, defined by mathematical models. Deviations of the actual response beyond an established tolerance causes the Nd:YAG laser system to adjust its parameters automatically.<>
