Manipulating Electrons with Intense Lasers
Laser Plasma Accelerators (LPA) rely on the control of the electrons motion with intense laser pulses . The manipulation of electrons with intense laser pulses allows a fine mapping of the longitudinal and radial components of giant electric fields that can be optimized for accelerating charged particle or for producing X rays. To illustrate the beauty of laser plasma accelerators I will show, how by changing the density profile of the gas target, one can improve the quality of the electron beam, its stability  and its energy gain , or by playing with the radial field one can reduce its divergence . I’ll 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 [5,6]. Finally I’ll give some examples of applications .
