The choice of the correct density profile is crucial in laser wakefield acceleration. In this work, both subsonic and supersonic gas targets are characterized by means of fluid-dynamic simulations and experimental interferometric measurements. The gas targets are studied in different configurations, and the density profiles most suitable for laser wakefield acceleration are discussed.
