Harry-- An additional thought--
What would happen if one were to have a different batch of metastable isomers, like radioactive isotopes, that are subject to stimulated decay with tuned EM radiation. That might give a real gamma ray laser, or at least a gamma (if nuclear origin) x-ray laser.

Note that the term "gamma-ray" in this context refers to the nuclear origin of the ray rather than its frequency. In this case the gamma-ray has a frequency in the optical range. Also notice that the thorium isomer is located within a compound of Lithium.

I'd be interested if someone knows of something like this. In the paper that Harry linked to [1], there was mention at the end of a claim in 1999 of being able to stimulate the 2.4 MeV decay of hafnium-178m2 with x-rays with less than 100 keV. This is a controversial result, for the energy needed to stimulate the transition is very low, and the result hasn't been confirmed yet. Eric [1] http://epubs.surrey.ac.uk/469/1/fulltext.pdf
