Overview

What is it?

Program for scientific research, which allows to simulate the phenomenon of self-focusing of different laser beams (including Gaussian, ring and vortex beams) in condensed media in different approximations taking into account noise.

Mathematical model

A mathematical model of beams self-focusing was obtained using the approximation of slowly varying amplitude and the terms responsible for diffraction and instantaneous Kerr effect are included. The model can be used to consider three-dimensional beams both in the axisymmetric approximation, and with both transverse spatial coordinates including ring beams with a phase singularity on the optical axis - the so-called optical vortices. The possibility of considering ring beams without phase singularity, as well as Gaussian beams, is supported. Implemented accounting for complex noise in the initial condition. In addition, two-dimensional beams are also considered.

    Simulating Self Focusing in Air

    Hey there, First of all - you did a great job posting this well written code here, it can really come in handy! I'd like to simulate propagation of Gaussian beams in air and have a few question:

    1. I don't quite understand what is meant by the "sweep method" when you progate the beam to achieve diffraction. Is this some kind of finite differences method? I've looked at the code in the class "SweepDiffractionExecutorX" and was quite clueless what happens in the __fast_process function.
    2. I didn't find a dependence on the pulse length in your simulations. How hard do you think it will be to add it to the existing framework?
    3. I've seen you have another program written in CPP of filamentation. Can you please elaborate in few sentences what is achieved there? I didn't find a wiki

    Thanks a lot, Ivan, Phd student in filamentation
