Patient’s skin temperature changes as function of time elapsed. Point forcing was applied (at t=0) in the form of a CO2RE laser pulse. Subsequent data points represent average values from the forcing area (2×2 pixels). Figure shows speed of human skin reaction upon pulse forcing – a single microbeam. Laser irradiation creates cone shaped laser channels – the so-called microscopic ablation zones (MAZ). MAZs are lined by a thin layer of coagulated tissue, together constituting the microscopic treatment zones (MTZ). The reaction on laser radiation - MTZ dimensions - differs at various distances r from forcing axis center.
