%X Cop-per and alu-mi-num are ma-te-ri-als that ha-ve tec-hno-lo-gi-cal, fun-cti-o-nal and ex-pres-si-ve va-lue in the con-tem-po-rary art and ar-chi-tec-tu-re. The-re-fo-re, studying the pos-si-bi-li-ti-es of pro-tec-ti-on of the-se ma-te-ri-als by using non-de-struc-ti-ve met-hod is of gre-at im-por-tan-ce when it co-mes to cul-tu-ral he-ri-ta-ge. The pa-per pre-sents the re-sults of in-ter-ac-ti-ons of la-ser light with wa-ve-length ¦Ë = 694.3nm (Ruby la-ser, Q-switch mo-de) and me-tal sam-ples, co-ve-red with a de-po-sit. The go-al of in-ve-sti-ga-ti-on was to de-ter-mi-ne the ma-xi-mum energy den-sity of the la-ser be-am which can be used to re-mo-ve de-po-sit and do-es not in-ter-act with the ba-sic ma-te-ri-al at the sa-me ti-me. The ef-fects of la-ser in-ter-ac-ti-on are in-ve-sti-ga-ted by SEM and EDX.
