MLL-Kolloquium: Prof. Victor Malka (Weizmann Institute of Science, Rehovot, Israel and Laboratoire d'Optique Appliquee, CNRS, Ecole Polytechnique, Palaiseau, France): Manipulating Electrons with Intense Laser Pulses


Laser Plasma Accelerators (LPA) rely on our ability to control the electrons motion with intense laser pulses [1]. The manipulation of such relativistic electrons allows a fine mapping of the longitudinal and radial components of giant electric fields with values that can exceed hundreds of GV/m [2]. This control is crucial to optimize the design of laser plasma accelerators for delivering ultra-short and ultra-bright energetic particle or radiation beams. To illustrate the beauty of laser plasma accelerators I will show some concepts that give improvements the quality of the electron beam, its stability [3] and its energy gain [4], and its divergence [5]. I will then show how by controlling the quiver motion of relativistic electrons intense and bright X-rays beam are produced in a compact and elegant way [6-8]. Finally I will show some examples of applications.
