Soft X-Ray Laser Interferometry of Colliding Laser-Created Plasmas in Semi-Cylindrical Cavities

PDF Version Also Available for Download.

Description

A table-top capillary discharge soft x-ray laser was used to acquire high contrast interferograms that map the evolution of dense aluminum plasmas created by laser irradiation of a 500 {micro}m diameter semi-cylindrical cavity with 120 ps optical laser pulses of {approx}1.1 x 10{sup 12} Wcm{sup -2} peak intensity. The measured electron density maps, that were compared with simulations, show that the plasma converges on axis, where it collides to form a localized region with density exceeding 1 x 10{sup 20} cm{sup -3}.
