optimal-chirp

Repository for different approaches for calculation of optimal chirp in laser pulse chirped in spectral domain. Here one can find 1) parameter scan on a linear grid, 2) analytic predictions, 3) more advanced numerical optimization (optuna).

ComptonSpec_classic.py - classes for classic calculation of Compton emission spectra taken from here.

generate_simulation_data.ipynb - generate and save simulation data.

Optuna_spectrum_optimization.ipynb - numerical optimization of chirp with optuna package.

plot_article_figures.ipynb - plot all figures present in the article

utils_simulation.py - utilities for obtaining the simulation data from parameter scan on a linear $\beta$ grid.

utils_analytics.py - utilities for analytic predictions

Folder data - used simulation and analytic data (obtained with generate_simulation_data.ipynb).

Folder Pearcey - numerical calculation of Pearcey 2nd derivatives which were used in Taylor correction procedure.
