Research output: Contribution to journalConference articlepeer-review


Laser ablation of biological tissue is associated with the occurrence of a peak temperature below the surface which can result in a rise in subsurface pressure and explosive tearing of tissue at the onset of ablation. Results are presented of surface temperature histories and fast video scan of porcine aorta irradiated by an argon laser at various powers. These results contain indicative signals of some of the processes associated with the onset of ablation.
