Hussar is a highly flexible Matlab framework for solving propagation problems.
The software is based on the mix of the Unidirectional Pulse Propagation Equation
approach and the "not necessarily slowly varying envelope" concept.
This composition enables an accurate modeling and small memory requirements.

On your laboratory PC
Hussar has been created for PC computers. 4GB RAM is enough for running simulations with 3 envelopes (SFG/DFG/OPA etc.) and 4 million points in the grid of each envelope (e.g grid of 128x128x256 points in 3D and 1024x4096 points in 2D simulation).

Linear pulse and beams propagation in birefringent media can easily be performed (in single step). All: 1+1D (T+Z), 2+1D (beam XY+Z, and pulses in cartesian TX+Z or cylindrical TR+Z coordinates) and 3+1D (TXY+Z) simulations can be performed. On the right a visualization of a Laguerre-Gaussian LP01 mode propagation in biaxial BiBO crystal is presented.
Three wave mixing
All three wave mixing phenomena: SHG, SFG, DFG, OPA, fluorescene up conversion, etc. can be simulated both in collinear and non-collinear configurations apart of 3+1D (TXY+Z) simulations for large beam sizes the fast 2+1D (TX+Z) simulation can be performed. An example of blue light pumped NOPA simulation is presented in the top of the page.
Supercontinuum generation in bulk materials is possible in 3+1D (TXY+Z) or 2+1D (TR+Z) cylindrical coordinates. Apart from SPM (= Self-Focusing), SRS, Self-Steepening and linear effects the photoionization (Multiphoton or Keldysh model) and current interaction (Drude model) can be included.
