Résumé

We study a X-ray laser (XRL) pumped by two 140 ps pulses from an IR laser beam. With the aim to regenerate the plasma gain with the second pulse, and then realise a double pass, we separate the two pulses by 800 ps. First experimental results obtained at LULI with Ne-like iron were very encouraging. In single pass mode, two saturated X-ray laser emissions have been observed with reproducible way. The gain values were respectively 15 cm^-1 and 12 cm^-1. This result qualitatively agrees with EHYBRID and Maxwell-Bloch modelling. We present the first far field pattern obtained in Ne-like iron and we deduce the two different positions of each XRL beam by subtracting images.
