摘要：

Two-dimensional photothermal displacement measurements were carried out on TiO2, ZrO2, and HfO2 coatings to uncover single shot incubation produced by 248 nm laser light at fluences below the damage threshold. The incubation behavior of the three coatings differs and correlates with the ratio of band gap to photon energy. The non-destructive nature of the photothermal displacement technique, its high lateral resolution, and its sensitivity for reading single shot imprints by an excimer laser lends this scheme a capacity for use in optical storage.
