Hydrodynamic simulations of plasma-based soft X-ray laser amplifiers
PROJECT DESCRIPTION: The main objective of this project is the first realization of three-stage laser chain in soft x-ray spectral region that is based on subsequent amplification of high-order harmonic pulse in two plasma amplifiers. The fully coherent ultrashort harmonic pulse will be first amplified in the transient plasma amplifier generated using technique of pumping under grazing incidence. This pulse pre-amplified to energy of several μJ will be further amplified in the quasi-steady state amplifier to reach energy of several mJ while keeping the optical properties of the seed. Using the technique of chirped pulse amplification we expect both the efficient extraction of the energy from the plasma amplifier by matching the seed duration to the amplifier gain duration, and generation of bandwidth-limited pulses. This will lead to creation of a user oriented beamline generating sub-picoseconds soft x-ray pulses of peak power higher or comparable to the currently operated and planned free electron lasers. This project will determine the fundamental parameters of individual plasma-based amplifiers as a function of pumping laser pulse parameters as energy, delays between pulses, spatial and temporal profiles, etc.
