The invention relates to a laser ablation method for coating an object with one or more surfaces, so that the object to be coated, i.e. the substrate, is coated by ablating the target, so that the uniformity of the surface deposited on the object to be coated is +- 100 nm. The surface of the coated object is advantageously free of micron size particles, and it is typically a nano technological surface where the size of separate particles is +- 25 nm at most. The object also relates to products made by said method.
