The aim of this work is to highlight what new technologies that are reaching us in the heritage sector can provide solutions to restoration problems that the traditional procedures have failed to resolve or that the result obtained was not the most suitable for proper conservation of archaeological objects. But in no way should these innovative methods be implemented in isolation, but in close cooperation and complementarity with traditional techniques; they should never be seen as a substitute but as an important, sometimes indispensable, support in the common task of preserving our most vulnerable Archaeological Heritage. In this context, it is becoming increasingly clear that laser is a relevant innovative application in archaeological materials that need to be restored, especially when these have highly resistant corrosion processes and corrosion packages, which traditional processes are unable to resolve with complete guarantees. This is particularly the case for many metal parts. For this reason, the laser applied in the restoration of these elements has excellent expectations, but these must be pursued in the short term by deepening research with the help of archaeometry, but also in the definition of a working protocol attached to the principles of conservation at the beginning of the 21st century.
