Laser Plasma Accelerators (LPA) rely on the control of the electronic motion with intense laser pulses . The manipulation of electrons with intense lasers allows a fine mapping of the longitudinal and radial components of giant electric fields with values that can exceed hundreds of GV/m , 10 000 times larger than the one used in conventional accelerators. With such control is now possible to realize laser plasma accelerators for producing ultra-short and ultra-bright energetic particle and radiation beams. To illustrate the beauty of laser plasma accelerators I will show 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 beams are produced in a compact and elegant way [6-8]. Finally, I’ll show some examples of applications.
