tnx. I also found some interesting data and info about energy velocity and its relations to photon lifetime , that is equivalent to group velocity but given as mean value of poynting vector(witch is almost same thing as the intensity ) and an energy density. I am interested: is it possible to...

Found it. if someone is interested look at article Bloch wave formalism of photon lifetime in DFB lasers.

Hello folks of physics. Can anyone tell me about some exotic photon lifetime definitions for photons in laser cavity? I mean, I looked in all sorts of books related to that topic, and the entire bunch of authors use the same definition: cavity exiting energy through dissipated power; or...
