My question is how to find the $n$ of a glass sheet with just aiming a laser beam to that.
I've got lot of ways that let me find the $n$ ( Refractive index ) but I need the whole part of the Refractive index that includes $n$ (Refractive index), $k$ (Extinction coefficient) and $α$ (absorption coefficient). ( because I want to calculate the amount of absorption of the glass sheet )
How can I find the all ( $n , k , α$ )? Can I find it by using the thickness of my glass sheet?
Notice that I want to find a way that uses a laser pointer
