This study was employed the Pulsed Laser ablation (PLA) technique with various Laser Energy Densities (LED) for investigating the production of TiO2Nanoparticles (TiO2NPs) by aid of titanium target immersed at Double Distilled Deionized water (DI water). Also, the various concentrations of Sodium Dodecyle Sulfate (SDS) as aqueous surfactant on size, shape, optical and structural properties of synthesized NPs by using Nd: YAG laser with a wavelength of 1064 nm was studied. Moreover, the created NPs were characterized by X-Ray diffraction (XRD), Secondary Electron Microscopy (SEM), Photoluminescence Spectroscopy as well as UV-Vis Spectrophotometer. The results show that, by increasing the LED, the number of NPs were enhanced while the size of them were decreased. Also, increasing the concentration of SDS solutions caused in decreasing the size of NPS, which all were smaller than those created at DI water. These results were obtained by UV/visible and photoluminescence analysis. XRD analysis show that the synthesized NPS in DI water and 0.001M SDS solution were almost amorphous however the concentration of 0.01 and 0.1M of SDS solution caused in creation of the crystalline structure. Eventually, the SEM pictures show that the samples which synthesized at SDS solutions had less compaction and sickness compare to those

of created at DI water.
