Monocrystal matrices of high-gap oxides are finding increasing applications as hosts of luminescent ions, typically rare earths (RE)s. Currently, RE-doped oxyorthosilicates, aluminum perovskites, and garnets (RE 2 SiO 5 -REAlO 3 -RE 3 Al 5 O 12 ) are

Experimental results are presented on the additional absorption of resonant light induced by the interceptive passage of a travelling packet of excitons in Cu2O, and on the possible implications this effect may have on the amplification of a Bose–E
