摘要

We present measurements of electron densities of plasmas with fs resolution. The plasmas are generated by laser pulses with different intensities at different time delays. Such plasmas are of great interest as preplasmas for transient, collisionally excited X-ray lasers. The prepulse is generated by stretching part of a 130-fs laser pulse of the ATLAS titanium-sapphire laser of our institute. Focusing this radiation to a line on molybdenum and silver targets generates preplasmas highly interesting to research directed towards a 10 Hz sub-Joule soft X-ray laser. The electron density is measured as a function of distance from the target by interferometry using a Wollaston prism. The ultrashort probe pulse allows one to obtain data as close as 10 - 20 μm from the target surface. Experimental data are compared with simulations using the MULTI hydrocode. The results allow optimization of prepulse-main pulse delay times and compare ablation from a hard (Mo) and a soft (Ag) material.
