Laser-induced expansion and contradiction dynamics of polymer films below ablation threshold was investigated with a time-resolved interferometry. Dynamic analysis of the morphological changes with a few tens nm and 120 ns resolution provides a new insight on photothermal mechanism. For reactive polymer films, laser-induced decomposition and following plume ejection processes was examined by applying further ns photographic method. Time-resolved spectroscopic measurement during excimer laser irradiation was very useful to identify transient species responsible to morphological changes. Recent advances and some future perspectives will be presented.
