Abstract

Summary form only given. Ultra intense laser systems with peak power in the 10 TW-1 PW range are difficult to focus close to the diffraction limit because of spatial phase aberrations. Reaching this goal is an important task when trying to get the highest possible intensity (typically >10/sup 20/ w/cm/sup 2/). In this paper, we describe an adaptive optics (AO) technique which has significantly improved the wavefront quality of the LULI 100 TW CPA Nd:glass laser. This AO system relies on a feed-back loop coupling a wavefront sensor and a wavefront corrector.
