Overheated metastable states in polymer sublimation by laser radiation

The mechanism of laser sublimation of polymers with low absorption coefficient and, as a result, with a volume nature of energy release is simulated. It is shown that the volume character of absorption of laser radiation together with the phase transformation leads to the existence of the overheated metastable state of material. The peculiarities of transient sublimation induced by laser action with the parameters similar for the formation of optical disks, are analysed.
