Abstract

A mathematical model of the transmission of heat by conduction was studied in a system consisting of thin layers on a solid support subjected to a laser impulse. The pulse length varied from 100 ns to 300 ns. It was shown (and confirmed by experiment) that, for a revolving disc, the heating effect has little influence on the active layer after sublimation recording is performed. The threshold temperature of this process for materials employed was in the range 180 to 200 degree(s)C. The calculated isotherms for the static mode are demonstrated and compared with experimental results for a case of an organic dye active layer with an absorption maximum at 780-850 nm.
