Abstract

The numerical study is carried out of amplified spontaneous emission (ASE) in an x-ray laser. Its gain zone appears in the laser-produced plasma at the prepulse irradiation of a thick optimally bent target and is characterized by an asymmetrical profile of the electron density. An effect of ASE transverse spatial coherence improvement is particularly investigated that takes place as a result of potential formation of a convex transverse density profile instead of a typical concave one. At the convex density profile one can obtain the partially coherent ASE whereas at concave density profile the ASE is practically non-coherent.
