High Power Femtosecond Lasers at ELI-NP

摘要

Specifications of the high power laser system (HPLS) designed for nuclear physics experiments are presented. Configuration of the 2 x 10 PW femtosecond laser system is described. In order to reach the required laser beam parameters, advanced laser techniques are proposed for the HPLS: parametric amplification and cross-polarized wave generation for the intensity contrast improvement and spectral broadening, acousto-optic programmable filters to compensate for spectral phase dispersion, optical filters for spectrum management, combined methods for transversal laser suppression.
