Paper Abstract

Joint theory of gamma-generation (GG) and radiation-heat regime (GG&RH) in active medium (AM) of (gamma) -laser (GL) is applied for the analyses of total world experience in the GL-problem in order to choose those nuclei-candidates, active media, GL-schemes which are indeed actual for the GL- creation. The classification of GL over a degree of the `comfortable conditions' for the GG is given. The GL-schemes could be `residential (Rsd)' (creation of excited laser- active nuclei, ELAN, from its parents directly in the site of AM) or `nonresidential (Nrsd)' (creation of ELAN out off the AM). It has been turned out that all `residential' part of the world experience does not fit for the realization of GL and can be considered only as a museum-piece. Any Rsd AM on the short-lived isomers must be inevitably blasted before the beginning of the GG. That `museum' part includes a lot of ideas: GG on long-lived isomers; line narrowing by radio- frequency or optical fields; creation of (gamma) -gain in the inversion less mixture of the excited and de-excited nuclei (amplification without inversion); super-dilution of work- nuclei in a matrix via multi wave Borrman effect; non- Moessbauer active media in plasma, gas or beam with its optical laser cooling, a lot of schemes (one-stage, two- stage, two-phase, two-step, two-photon, etc.). The exception could be only Rsd GL pumped by another GL. But the Nrsd part of world experience had stood yet all strict tests of that joint theory.
