Development of a X-UV Michelson interferometer for probing laser produced plasmas with a X-ray laser

We have developed and used a soft x-ray Michelson interferometer to probe large laser-produced plasmas. The aim investigated is to obtain electron density profiles and thus important informations on the plasma dynamic. This paper describes our design and presents some preliminary results using a nickel-like x-ray laser operating at 13.9 nm. Wewill present numericals results which show the interest of using x-ray laser to probe laser-produced plasma by interferometry.
