Abstract

Laser ablation is recognized as one of promising methods for microfabrication of polymers. Irradiation by an intense excimer laser produces a high density of excited states and reaction intermediates, causes a temperature rise, removes surface layer, and gives rise to morphological changes. This nonlinear photochemical behaviour was investigated by nanosecond time-resolved spectroscopy and nanosecond dynamic photography just upon laser ablation.
