Simulation strategy on efficiently combining 3+1D and 1+1D numerical simulations of high energy pulse post-compression in multiple thin plate compressor. While the main part of the optimization takes place in the 1D space, the final result describes the electric field of the pulse in the spatio-temporal space, and effected by third order nonlinearity, Raman-scattering, ionization and linear dispersion. The technique is compared to an experimental result where single cycle regime was reached, and the validation showed high accuracy. This method enables further optimization of post-compression for secondary sources, such as high harmonic generation and ion acceleration.
