The coherent and incoherent pumping of a gamma ray laser with intense optical radiation

摘要: Both the coherent and incoherent pumping with intense optical radiation of electromagnetic transitions in nuclei were modeled this work. In first case anti‐Stokes upconversion conventional laser was shown to be a potentially viable means for γ‐ray laser. With most favorable possible arrangement nuclear energy levels, threshold stimulated output at 10 keV might reached few tens Joules isomeric media lifetimes order years. Whether such an excited states actually exists will require additional experimentation. material, resonant excitation energetic by x from plasmas or exploding wires results similar those pumping. Thresholds could as low hundred into primary pulse producing x‐ray flash. Again possibilities found critically dependent upon unknown parameters, particularly efficiency conversion input rays. The overall concluded reasonably encouraging need spectroscopic data clearly defined.
