Finite element method is used to solve the diffusion equations of light and heat simultaneously, to calculate the temperature field in laser tissue interaction. The model suggests that a wavelength of 585 nm and continuous pulse of 0.45 ms with energy density of at least 6 Jcm-2 are recommended for effective flashlamp pulsed dye laser treatment of port-wine stains. The model predicts that vessel smaller than 20 μm will be spared and vessels larger than 200 μm in diameter will be partially coagulated. These results agreed with previously published pathological examination.
