Description

One- and two-photon spectroscopy is used for the investigation of the nature of the lowest electronic excitations and their relaxation in YAG and YAP crystals. The coexistence of two types of electronic states (the metastable excitons and the electron-hole continuum) having different relaxation ways has been observed in the exciton absorption region. The peculiarities of the electronic state spectrum observed are supposed to be connected with the complexity of the electron structure of the oxides investigated. ((orig.))
