Resolution of gamma-ray laser dilemma
Additional Document Info
Laser driving of bounded electronic transitions in atoms provides an efficient manipulation of nuclear transitions by the Moessbauer spectroscopy. Under certain conditions, it leads to the suppression of resonant absorption by 3-5 orders of magnitude and a reduction up to the level of off-resonant losses in the host matrix. In turn, suppression of the resonant absorption reduces the requirement for incoherent pump by the same amount. This allows the active nuclei to be pumped into the host lattice without destroying the conditions of both Moessbauer and Borrmann effects. Moreover, it allows resonant pumping at the operating transition, increasing the efficiency of the incoherent pump by 1-2 orders of magnitude.
