Description
The project focuses on simulating high-harmonic generation (HHG) driven by Bessel-Gauss beams, which can be, for example, used to construct a spectrally selective generation scheme (https://journals.aps.org/pra/abstract/10.1103/PhysRevA.109.033517). To model the system, numerical simulations combining the microscopic atomic response and macroscopic field propagation are conducted using the open-source Modular Multiscale Approach toolbox (https://mma-hhg.github.io/). This allows us to quantitatively describe all stages of the HHG process, including nonlinear laser propagation and various approaches to the microscopic response. We utilize this tool to map the key parameters for optimizing monochromatic XUV output while maintaining a fixed modulation geometry.
