**Brief idea of research interest: The world is made of materials; our quest is to explore it. The exploration of dimensionality aspects of phase transitions as well as all advanced production of devices requires good knowledge of materials. That knowledge is our mission. Theoretical physics and experimental physics are challenging fields that require a lot of background. For these reasons: I do Theoretical and Experimental research in these topics; # Laser, Microscopy & Spectroscopy; Design and construction laser systems and study the electrical and optical properties of these systems in order to use them as tools for laser applications, e.g. for human treatment, Lidar to detect the vegetation area, forest, mountains, roads,……etc and pollution in air and water … # Designing and constructions Two photon / multi-photon laser-scanning microscopy which is the latest technique to be introduced in the filed of fluorescence laser scanning microscopy and Second Harmonic Imaging. # Designing and constructions Multi-functional Two/multi-Photon Laser Scanning Microscopy (MF-TPLSM) by combing three platforms of laser scanning microscopy; the fluorescence microscopy, harmonic generation microscopy and polarizing microscopy for detecting the Second Harmonic Generation (SHG) signals in the forward and backward directions as well as the two photon excitation fluoresce (TPEF). # Confocal laser scanning microscopy # Wide-field fluorescence microscopy # Scanning electron microscope and Transmission electron microscope # Design and construction Microscope systems # Laser & Spectroscopy # Designing Optical Tweezers for any kind of Microscopy to trap the moving object # Photonic Crystals & Biophotonics # Nonlinear crystal (nanocrystal and Bulk crystal) # Second, third and fourth Harmonic Generation # Condensed Matter Physics (Theoretical and Experimental); calculate the electronic structure, optical (linear and nonlinear) properties and the other properties, searching the promising materials for Li-ion rechargeable batteries. Also calculate the properties of low dimensional nanoscale materials such as nanotubes, nanowires, and thin-films, etc, by using the density functional theory (DFT). In these calculations I have used Full-Potential Linear Augmented Plane Wave (FP-LAPW) method as embodied in the WIEN2K code. Also I have used The Linear Muffin-tin orbital (LMTO) method, VASP code, and some other codes. Also I am Editor of three international journals, and reviewer for some others; Phys. Rev. B, Phys. Rev. Letts,..etc.
