Source setting for discrete wavelengths

  Hello Everyone
  Is there any way to use three different wavelengths that are randomly apart from each other for a single source?As generally for broad band excitation what we do we provide a range of wavelengths then make them linearly apart from each other to see responces on sliced wavelengths.But what if i want to excite the device with 430nm,467,and 480nm?as if i select a span then set frequency points that are apart by 1nmthen it would be really time consuming as the solver would do siimulation for the entire range.Plz guide in this regard.

  It is absolutely not necessary for linear optics to use discrete wavelength. You can set a broadband source, but set the monitor to only record those 3 or any number of specified wavelengths.
  If it is nonlinear , then you may need to add 3 different sources centered at the desired wavelengths. Please refer to this example to get quasi-monochromatic source: https://optics.ansys.com/hc/en-us/articles/360041722614-4-level-2-electron-material-model
