Various schemes exploiting two-quantum nuclear transitions for the generation of coherent gamma radiation (stimulated anti-Stokes and stimulated two-quantum de-excitation of isomeric nuclei in an active medium with the hidden population inversion of nuclear states and the ignition of an avalanche-like stimulated gamma-emission by counterpropagating X-rays) are discussed.

Igniting of two‐quanta gamma‐ray emission by two external counterpropagating photon beams involves into stimulated process all the nuclei no matter what their randomly distributed velocities are. Such kind of two‐photon emission gives rise to dynamic non‐linear distributed feedback, thus any mirrors or other reflecting structures are not needed. Both effects together result in avalanche‐like burst emission of all the excited nuclei.
