It only makes you, in your own eyes, look smart.
My guess is that you don't know why my ideas won't work, but don't want to admit they they could, as you've already said that they wouldn't and that would mean that you were wrong. You therefore ignore my comments, except the parts that help your belief that I'm stupid, or ignorant, or have an attitude problem, or whatever else will make me look bad. This is especially evident when I post an explaination of exactly what my position is and what I want to know, including why I think that, and you latch onto the last sentence where I point out a few minor mistakes you made.
I would suggest that it is YOU that has an attitude problem, as your behavior is more like that of an argumentative child than that of a teacher.
I'm a little surprised at what has NOT come up in this discussion. First, surely the point is that gamma radiation arises from quantum transitions
within the nucleus, which involve energy changes several orders of magnitude greater than those involved in electronic transitions, whether atomic or molecular. It is thus obvious gamma rays are far too powerful to take part in any process involving bound electrons in an atom or molecule - hence PhDemon's dismissal of the idea that a conventional "lasing material" as you call it, might be able to handle gamma rays.
To my knowledge, no gamma ray laser has yet been built, but it were, it would depend on creating a population inversion of excited
nuclear states, not electronic states.
I am not aware of any process whereby an
excited nucleus can return to the ground state via
transfer of its energy to the surrounding electrons in the atom. So I do not see how you can get gamma ray photons converted to visible ones in the way you suggest. If you want to progress this idea of yours, I think this is the issue you need to address.
