In this paper the onedimonsional Stefantype model for the heat effect of highirradiance laser on biotissues and the inverse problem identification are adopted to obtain a relational expression for calculating the ablation depth in laserirradiated tissues, in which the complex nature of actual situationthe multidimensional problemis taken into account.

The damage morphology, and threshold fluence as a function of pulse duration and the dependence of ablation depths on the pulse fluences are measured.

The relation between damage threshold,ablation depth and laser pulse duration,wavelength,energy fluence is studied with the model.
