Abstract The present work research had as a goal build a experimental system to Laser Induced Breakdown Spectroscopy (LIBS) that was applied to arqueological sample analysis. LIBS system was formed principally by an Ocean Insight HR4000 CG-UV-NIR mi niespectrometer, a Nd:YAG laser of 1064 nm wavelenght and a optical fiber. Study objects were three metallic arqueológical sample found in Colonial Church from Huanchaco, Trujillo Perú, that belonged to Viru Culture. It was used a fluence of 3,5J/cm2 aproximately, obtained for a laser pulse energy of (10,0 ± 0,5) mJ. LIBS espectrum was obtained in an aire medium, Andes LIBS software was used to analized the spectrum and found that the arqueological samples was made principally of copper (CuI). The spectral lines identified were those belonging to the wa velengths of: 324.75 nm, 327.4 nm,458.7 nm, 510.55 nm, 515.32nm, 521.82 nm, 529.25 nm, y 578.21 nm. It was proved that this LIBS system is useful to determined the element compositión of metallic archaeological samples
