Abstract :
A method for measuring laser ablation threshold energy with a high-speed framing camera is presented. To demonstrate the utility of the technique, the threshold energy for pulsed holmium laser ablation of liver was measured. The measured threshold radiant exposure of 30±3 J/cm2 is in good agreement with values previously determined by alternate techniques. In addition to providing a rapid and reproducible measurement of laser ablation threshold, this technique also provides insight into the physical mechanisms of ablation
