摘要：

Just upon laser ablation of anthracene-doped polystyrene films, temporal profile of the dopant fluorescence was measured and compared to the computational results based on cyclic multiphotonic absorption in the ground state, the first excited singlet state, or the lowest triplet state. Calculated temperature rise during laser irradiation is non-linear to the laser intensity and indicates that rapid internal conversion in the triplet manifold is most effective to generate heat at the irradiated surface. Deuteration effect of anthracene is also discussed.
