The nuclear analog of the ruby laser is shown in Fig. 1. It embodies the simplest concepts for a gamma-ray laser. Not surprisingly, the greatest rate of progress has occurred in this direction. Studies aimed at upgrading the nuclear database have yielded a singularly useful technique for the calibration of large pulsed bremsstrahlung sources used for pumping in the region from 150 keV to 1.3 MeV. In addition, experiments utilizing bremsstrahlung from a 6 MeV linear accelerator have indicated the possibility of accessing the broad octupole states above 2 MeV in 111Cd, 113In and 115In. Effective integrated cross sections (πbaboσoΓ/2) on the order of 104 cm2 keV were observed. Finally the upconversion pumping, shown schematically in Fig. 2, of the first of 29 potential candidate materials for a gamma-ray laser was reported.
