Volume 1, Issue 3 , July 2017, Pages 9-16

Abstract
  In this paper, Pulsed Laser Deposition (PLD) process at the presence of a background gas was simulated using the Monte Carlo method. Specifically, growth of aluminum metal in xenon background gas at the pressure of 50 mTorr was simulated. Target-to-substrate distances of 10, 15, 20, 25 and 30 mm are ...  Read More

The Dephasing Length Increment in Laser Wake Field Accelerator

Mehdi Asri; Iman Kamel Jahromi

Volume 1, Issue 3 , July 2017, Pages 17-26

Abstract
  Solving of laser wakefield equations in the presence of external magnetic field, we observed that the dephasing length and final energy of accelerated electron by wakefield depend on polarization of laser pulse and applying direction of magnetic field. As for the case of applying magnetic field in the ...  Read More

Studying Simulation of Effective Parameters on Charge State of Ions in Interaction of High Power Laser with Argon Nano - Cluster

Hosein Ghaforyan

Volume 1, Issue 3 , July 2017, Pages 27-34

Abstract
  In this paper we studied the interaction of femtosecond laser pulse with atomic cluster of Ar. Ionization, heating and expansion of the cluster was the results of this interaction. Following this process, hot and energetic electrons and high charge state of ions were produced. By changing the characteristics ...  Read More

Study of Localized Modes Between Defective Multilayer Structures and Conventional or LH Material

Zahra Eyni

Volume 1, Issue 3 , July 2017, Pages 35-42

Abstract
  In this paper, the TM localized waves produced at the interface of homogeneous media and defective photonic crystals has been studied. The considered homogeneous medium can be a left-handed or a conventional material. It was found that for the conventional medium, in case of defect in the refractive ...  Read More

reza Salmani; Ali Navid

Volume 1, Issue 3 , July 2017, Pages 43-50

Abstract
  In this paper, we present an effective scheme to control molecular alignment and orientation by interaction of molecule with Two-color femtosecond laser pulse. For this purpose, we use numerical solution of the time - dependent Schrodinger equation for a linear molecule of carbon monoxide to achieve ...  Read More

Volume 1, Issue 3 , July 2017, Pages 51-58

Abstract
  According to the recent remarkable developments of lead halide perovskite solar cells, investigation of the optical and electronical properties of perovskite structures seems necessary. In this paper, firstly Organic–inorganic CH3NH3PbX3 perovskite hybrids with X= Cl, Br and I were prepared by ...  Read More

Influence of the Orientation of Optical Axis on the Behavior of Anisotropic Photonic Band Gap

Zahra Mojarrad; Robabeh Talebzadeh

Volume 1, Issue 3 , July 2017, Pages 59-66

Abstract
  In this study, the transmission spectrum of an anisotropic photonic crystal using a transfer matrix method for both of polarization state TE and TM. We showedthat the Bragg gap, so called, anisotropic Bragg gap is created in transmission spectrum due to existence of anisotropic layer in structure. The ...  Read More
