Hello,
I'd like to understand what complex refractive indices can be found in nature. Specifically I am trying to get an order of magnitude estimation on the imaginary part of the refractive index. In what type of active lasing medium would this be the largest ? and how large would it actually get ? 10^-4 ? 0.01 ? 0.1 ?
It sounds like a simple question, but I had a surprisingly hard time getting a simple answer from the literature.
Can anyone help ?
