✦ Synopsis

Background and Objective

: An expression describing the ablation crater shape as a function of lateral fluence distribution has been derived in a recent paper by Ostertag et al. [Lasers Surg Med 1997; 21:384-394]. Study Design/Materials and Methods: The ablation model presented therein is improved by taking into account the influence of the ablation front inclination on the ablation dynamics. Results: The resulting crater profiles deviate from the previously predicted ones (which reflect the Gaussian fluence distribution of the impinging laser beam) progressively with increasing pulse fluence. Conclusion: The ablation front inclination must be taken into account to predict the ablation crater shapes and volumes correctly.

Background and Objective: Absorption of a short laser pulse produces high thermoelastic stress in the irradiated volume. The relaxation of this stress at a free (tissue-air) surface leads to tensile loading, resulting in mechanical spallation. Using model substances, we investigated the role of this
