Re: Optical Simulation: FOCSS

Jonathan and Dave

I have come across software called COMSIS 8 at, which deals
with laser chirp and non linearities as well.  Hopefully you know some French. 

Optisim made by has CW Lorenztzian laser source and 
rate equation laser source.

The above software only handles single mode lasers and fibers.

Good Luck,
