Outline of Final Research Achievements

High-order harmonics generation due to singularities formed by an intense laser in underdense plasma is investigated with the help of analytical methods and multi-parametric PIC simulations. A control over the onset of the high-order harmonics generation is demonstrated using tailored plasma profiles. A highly efficient generation regime is found. A dedicated simulation explained recent experimental finding of point-like x-ray sources in plasma irradiated by the J-KAREN laser.
