Time-Resolved Analysis of High-Power-Laser Produced Plasma Expansion in Vacuum

Here we consider the results of an experimental investigation of the temporal evolution of plasmas produced by high power laser irradiation of various types of target materials. The experiment was performed at the LULI Laboratory (Ecole Polytechnique, Paris). We have developed a method to analyze time‐resolved streak‐camera images and analyzed a number of results obtained with various materials.
