Time-resolved studies of head-on colliding laser plasmas

By focusing a laser beam through a small capillary made of polyethylene onto a second target made of glassy carbon placed behind it, two plasmas are created. A cold plasma is obtained by ablation of the capillary wall, and a hot plasma by ablation of teh second target. These plasmas expand directly toward each other, producing a head-on collision with a large relative velocity of the colliding plasma clouds. The dynamics of the collision and the formation of the collision zone itself is studied by fast XUV spectroscopy. It was found that the collision zone is almost stationalr and long living, being visible long after the plasmas that created it disappear out of view.
