Hello, in principle yes, since it is the same equations that govern the process. However, the code listed accounts for the presence of a cavity and propagation is repeated for many round trips. You could alter the code to propagate for a single pass through the gain medium. I would recommend the program SNLO, if you are looking to perform simple calculations of OPG experiments.
Hi, thanks for your reply. I need to simulate the generated OPG spectrum. seeding the OPA with the quantum noise, may be this model is suitable for me.
The model is a single frequency model, as this is what we had in the lab. So the model would need to be extended to include broadband signals. The spectrum was not a big concern for me, so I did not investigate that further. However, you could take the Fourier transform of the generated signal and idler pulses and see what you get !
Ok, thank you for your help. I will do a try.
For broadband signals, you would need to implement something similar to this model, without the cavity part: https://as-photonics.com/publication_files/OPO/Josab16b.pdf
Best of luck
ok, thank you. I will firstly remove the cavity part of OPO model. if the code could work, I would implement the simulation of broadband signal with this model. could I do this in sequence?

You first need to identify what physics you are interested in and what is relevant with your project. Is it necessary to include diffraction/spatial effects in your investigation ? It is also important to understand what time regime you are working with. Is it CW, ns, fs? Depending on the time regime, you might need to include/exclude certain effects to get a realistic simulation of the output spectrum (such as Dispersion). It is always good to start off with a simple model and ensure its correct and makes sense first, before adding more complicated effects.
sorrry to disturb you. could the model be used to simulate the OPG process
best regards
