Description
The giant longitudinal electric fields produced in laser plasmas can be used to generate, in a compact and reproducible way, energetic electron beams with tuneable parameters. In those laser plasma accelerators, different injection schemes have been demonstrated such as the forced laser wake field [1], the bubble/blow out regime [2], or the colliding laser pulses [3] that offers the possibility to control the electron beam parameters. These electron beams with peak current of a few kA [4] are of interest for a very broad range of applications in medical, biological, chemistry or material science domains [5]. They are also of major interest for the production of very bright X/gamma ray beams [6]. I report here on the evolution of laser plasma accelerators developed at LOA and on very recent achievements we performed on the applications side.
