    Acousto-optics science deals with the interaction between sound and light waves. Acousto-optic waves are most important in transferring signals through the communication systems, since modulating signals takes a great advantages in the field of communication engineering, bio-medical, laser beam deflection and laser intensity modulation. The aim of this work is to simulate the fundamentals of an Acousto-Optic Modulator.

         A theoretical and computational investigation was carried out in the field of laser-plasma interaction using the Finite Difference Method to study the acceleration of electrons with non-relativistic elocities in a non-magnetized and magnetized collisionless plasmas.First, a (Nd:YAG) laser pulse of  25 fs duration and 5x10  intensity was assumed in the present study.When this laser pulse was allowed to nteract with a stationary electron in vacuum, it was found that the electron is accelerated during the interaction only and returns to stationary state af

   Many applications  in industry,  depends on dissimilar material joints.Due to the difference in chemical, mechanical and thermal behaviors of materials,  the joining of dissimilar materials presents a challenges, significantly different than similar materials joining ^[1]. Bonding as a subdivision of both solid-state and liquid-phase welding, is a joining process wherein the principal mechanism is interdiffusion of atoms across the interface.
