Abstract

We will present a thermal model for laser pulses with pulse widths small compared to the material's thermal time constant. This model will then be used to generate computer plots of the zones of vaporized tissue as well as the predicted tissue temperature rise. Using published values of absorption coefficients, we will predict the vaporization energy thresholds for Er:YAG (2.94μm), Ho:YAG (2.1μm) and CO₂ (10.6μm) laser pulses. We will also examine the extent of the thermally denatured zone surrounding the zone of vaporization. Using typical energies available from these lasers we will then predict material removed per pulse, and per second.
