Abstract: In this work laser-induced breakdown spectroscopy (LIBS) has been used to identify the elements that contains in dates fruits (Gondela) which collected from Goshabi Governorate in Northern Sudan. The sample was exposed to pluses nitrogen laser 337.1nm with power (100, 200) mJ and duration 10ns. The obtained results showed that the Gondela dates fruits contains considerable amount of elements when used power 100mJ such as Xe II, WI , Fe II, Zn I, Ar I, Cu II ,Na II , Ne II , Cr I and Th I, while W I , Xe II , Fe II , Mo I, Na II , Ne II , Mg II , Ra I , Th I , Xe I , V I , Ti I , Fe I , Mn I , V II, Co II and K I when used power 200mJ.
