Abstract

Ablation of biological targets by highly-absorbed infrared laser pulses (duration 200 microsecond(s) ) is explained using a model that takes into account tissue liquefaction. The generation of a liquid layer in tissue leads to an enhancement of the drilling efficiency and to a reduction of the evaporation rate. Experimental drilling-depth and recoil-momentum data are explained by a combination of evaporation and ejection.
