A highly sensitive nanosecond time-resolved interferometry was developed and applied to study dynamics of morphological changes of a thin poly(methyl methacrylate) film doped with biphenyl upon laser ablation. It was confirmed that morphological changes started during a nanosecond excitation laser pulse and then followed by an ejection of ablated polymer fragments. Even below the ablation threshold, a transient expansion of the polymer film, followed by slow contraction, was observed. New features of laser ablation dynamics were clarified.
