      In this work, the structure and optical properties of Lead sulfide PbS nanostructure were studied. Thin film deposited on glass substrates were prepared by pulse laser deposition Nd:YAG laser at (1064 nm) wavelength with a various laser energies (200, 300, 400 and 500) mJ was used. The effect of changing the laser energy on the structural properties has been studied using atomic force microscope (AFM) and X-ray diffraction technique. It has been observed that the film formed is of the polycrystalline type and the predominant phase is the plane (111) and (200). AFM assays also showed that the minimum granular size obtained was (59.43 nm) at laser power (200 mJ). The results revealed the possibility of preparing nanostructure with medium grain size of (68 nm). As for the optical properties, the effect of changing the laser energy on nanostructure was studied, and it was found that they have direct allowed transitions in the range of (1.47 to 1.80) eV.
