Does it make sense to simulate 2 independent sources?

  I am doing a Raman enhancement effect by exciting a source of UV wavelength into a semiconductor material. So I did the simulation by adding 2 total - field scattered - field sources: 1 source with wavelength 633 nm and 1 source with wavelength 365 nm. To observe the change of electric field strength distribution. Does this make sense?

  Since Raman enhancement is simulated linearly, it is not recommended to use two different sources at different wavelengths. Otherwise the signal normalization will be difficult as their time signals are not the same. https://optics.ansys.com/hc/en-us/articles/360034394234-Understanding-frequency-domain-CW-normalization
  I would suggest that you use a broadband source from 365 to 633nm, and monitor only the two wavelengths if thet are the most desired, or monitor the broadband response.
