Hello there. I am wondering if anyone can shed some light on this topic. I am searching all over the Internet to find reliable sources on the possibility of gamma ray lasers. I know that it requires an atom that can be "pumped" without spontaneously emitting its energy so it can be triggered by stimulated emission to provide photons to lase. Also I can't seem to find reliable solid physics on the factors associated with the melting and vaporisation depth of lasers. This is required to make my own decision about the gamma ray laser being a superior weapon as it will allow me to calculate what materials it can burn through and timings etc. If anyone could offer any help that would be fantastic!
