If you have not figured , log the .exe output to a file and open that in Python for further simulation ... 

Hi Tony,

In case you are still looking for a simulation tool, you might want to check out my project PyFiberAmp. I'd be glad to help you further if you decide to give it a try.

Thank you very much Joona. this is exactly what I was looking for. I will spend some time on it and ask you further help in case...

Hi Joona Rissanen

Does your model work for Erbium Doped fibers as well?

Thanks in advance

Hi Imrul Kayes,

The code works for both Yb-doped and Er-doped fibers. You simply need to provide the effective absorption and emission cross sections and upper state lifetime of your ions. There is an example on how to do it. The current model assumes a two-level system, so excited state absorption in Er cannot be simulated yet.
