## Main Question or Discussion Point

This is a question for knowledge not for any assignment, but I was wondering what type of equation describes the damping or extinction that the light beam coming from a laser endures. I googled and couldn't find much although I may be using the wrong terminology. Could someone point me toward a reference or enlighten me on the subject?

I assume that the density of air will come into play as there will be more scattering and so will the distance but I can't find any equations or even begin to derive my own.

Thanks
