A method is described for the reliable production of reproducible multilayered targets for laser ablation rate studies using time‐resolved x‐ray spectroscopy. The targets consist of alternating layers of plastic and evaporated metals whose thickness and uniformity were examined by weighing and by SEM micrography to be suitable for experiments. The plastic layers are deposited by a dipping technique using various concentrations of polystyrene and Formvar solutions. The resulting thickness of the films versus the concentration of the solutions is reported. In addition, an application of submicrometer Formvar films for use as sub‐keV x‐ray filters is described.
