In recent years, the research on graphene has received a lot of interest to both academia and industry due to its outstanding physical and chemical properties, and its potential for various applications. Due to this, several methods are used to produce either pristine graphene or doped graphene. Among these methods, Pulsed Laser Deposition (PLD) has proved to be an alternative route for producing graphene layers from amorphous carbon thin films, due to many advantages including the controlled film thickness and dopant compositions in the films [1]. The present talk will give an overview of the ability of PLD to fabricate graphene and doped graphene films, mainly with nitrogen or boron atoms [2]. The growth mechanism will be highlighted based on XPS investigations in situ during graphene growth. The graphene films characteristics depending on the substrates and the influence of synthesis process parameters such as initial amorphous carbon (a-C) thickness, laser energy and annealing temperature on the growth of graphene are discussed mainly based on Raman analysis. Investigations of electrochemistry properties of nitrogen-doped graphene synthesized by PLD are emphasized. The results show that functionalized electrodes with nitrogen-doped graphene exhibit excellent reversibility, close to the theoretical value of 59 mV, and very high sensitivity to hydrogen peroxide oxidation [3]. The present talk will help researchers to get an overview of the interest of PLD for graphene and doped-graphene synthesis. References 1.Y. Bleu, F. Bourquard, T. Tite, A.-S. Loir, C. Maddi, C.
