Title:	Dynamical Description of Transient X-Ray Lasers Seeded with High-Order Harmonic Radiation through Maxwell-Bloch Numerical Simulations
Abstract:	The Maxwell-Bloch code COLAX has been upgraded to describe the seeding of short pulses of high-order harmonics into an x-ray laser amplifier pumped in the traveling wave transient regime. The amplification is shown to be a dynamic, two-stage process: the atomic dipoles of the lasing ions are first coherently excited by the short pulse, and subsequently generate a radiation wake which is amplified along its path through the plasma. The physical background of the code will be presented and the first simulation results obtained will be discussed.
