I am, as are probably quite a few of us here, a bit curious as to why exactly silver gallium selenide is such an amazing nonlinear optic, allowing 100% efficiency. Well, I did a dive into the RefractionIndices.txt file, and lo and behold, Silver Gallium Selenide has no entry at all for the k value - where all other materials do have one, and from what I can tell, the k value in the complex refractive index governs the absorptive properties of the material. Even more interestingly, this k value appears to be either missing or set to 0 for the refractive indices of all lasing media, nonlinear optics or other transparent materials.
Could someone with more of an understanding of optics/the complex refractive index chime in and tell me if this should be that way or not?
