Fig. 1. SEM images of long-pulse hybrid materials on glass and AAO. AlOx: cross-section images of AAO substrates (A and B) and a tilted view on (C) glass. TiOx: a tilted cross-section (D) and top-view (E) on AAO, and a tilted side-view on (F) glass. ZnOx: (G) cross-section of AAO and tilted side-views on glass with an intact (H) and broken (I) meniscus.
