  Hello, how can I modify the parameters of the four-level two-electron material model by my desired gain material? I need the gain material to emit the light in different frequencies how can I change the parameters to have the new gain material with a new spectrum? many thanks. https://optics.ansys.com/hc/en-us/articles/360041722614-4-level-2-electron-material-model

  some more help can be found:

  you can also check the original paper Chang and Taflove, Optics Express, 2004, 3827-3833.
  you should be able to modify the material properties based on the frequency you desire:
  to create proper gain at the desired frequency.
