Paper Abstract

In present work an analysis of the existing experimental data has been carried out on the ablation of biological tissue (skin, cornea, bone) under high-irradiance laser beam ~109W/cm2 at different wavelengths λ = 0.266, 0.532, 1,064, 2.7, 2.8, 2.9 μm. Comparison of the dependence of the ablation threshold values versus the intensity and wavelength of the single incident pulse to the data obtained in experiments on hgih power pulses interaction with organic low-density targets of agar-agar allows to reveal some common mechanisms. For the above threshold intensities, the temporal pulse shape becomes decisive and together with tissue transmittacne at a definite wavelength determines the depth and character of tissue disruption and may be changed according to therapeutic destination.
