Abstract : The nuclear-pumped laser could, in theory, provide a small, efficient source of coherent optical radiation capable of many years of untended operation. The main deterrent to its realization is existence of the laser cutoff effect: quenching of laser action by high energy radiation. An hypothesis based on electron-induced superradiance is in agreement with the experiment. A low threshold laser material, YAG:Cr-Nd, has been found to resist this effect up to doses of 960 rads.
