This research was employed the Pulsed Laser ablation (PLA) technique with various Laser Energy Densities (LED) for investigating the production of TiO2Nanoparticles (TiO2NPs) with aid of titanium target immersed in Double Distilled Deionized water (DI water). Furthermore, the various concentrations of Sodium Dodecyl 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 planned. Moreover, the created NPs were considered by X-Ray diffraction (XRD), Secondary Electron Microscopy (SEM), Photoluminescence Spectroscopy as well as UV-Vis Spectrophotometer. The results clearly show that, by increasing the LED, the number of NPs was enhanced while the size them was decreased. Also, increasing the concentration of SDS solutions caused by 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 shows 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 the creation of the crystalline structure. Eventually, the SEM pictures show that the samples synthesized at SDS solutions had less compaction and sickness compare to those created at DI water
