In this article, we report a review of recent results obtained by focusing a nanosecond laser beam onto a gas jet target. The benefit of gas jet targets for the generation of homogeneous and large scale plasmas, which are of interest for a MJ program will be presented. Additionally, laser beam smoothing, the studies of parametric instabilities (Raman and Brillouin) and applications in atomic physic in warm and dense plasmas will be discussed. %G English %L hal-00502846 %U https://polytechnique.hal.science/hal-00502846 %~ X %~ ENSTA %~ CNRS %~ X-LOA %~ X-DEP %~ X-DEP-PHYS %~ PARISTECH %~ ENSTA_LOA
