Abstract
Pulsed laser melting and evaporation of superconducting ceramics is si mulated numerically. The dynamics of both phase fronts (evaporation an d melting/solidification) are analysed during the whole thermal cycle. The appearance of overheated metastable states in the solid and liqui d phases as a result of the phase front dynamics and the volume nature of laser energy release is shown. The influence of the volume absorpt ion coefficient (or wavelength of laser radiation) on heat phenomena i s analysed.
