Acherus¶

An open-source laser pulse filamentation (2+1)-dimensional solver

🚀 Key features of acherus:

Input beam models: Gaussian spatiotemporal profiles including chirped and lens-focused beams.
Dispersion models: full or partial chromatic dispersion using Sellmeier semi-empirical equations.
Ionization models: multiphoton ionization (MPI) or general Keldysh-PPT theory rate predictions.
Python implementation with exposed API: access to modules, classes, functions, and core simulation objects.
High performance matrix operations using numpy and scipy compiled libraries for fast, GIL-free computation.
Built-in 1D-3D visualization tools for post-processing and on-the-fly simulation monitoring with Matplotlib.
Optimized memory management and multithreading using ThreadPoolExecutor shared work pools.

🧩 Other features of acherus:

Decoupled split-step Crank-Nicolson (SSCN) solver for simpler scenarios.
Optimized output storage (HDF5 format) and post-processing with h5py library.
