“…Depending on lifetime CC in oxide laser crystals can be divided into stable color centers (SCC) existing in crystals in the time range from seconds to a few months or years, and transient color centers (TCC), which lifetime lies in the time range less than one second after the end of excitation [4,5]. SCC usually are responsible for passive energy losses, and TCC -for active energy losses [4,6,7]. There is some correlation between concentrations of SCC and TCC.…”

The work is devoted to investigation of stable color centers (CC) that are created in Gd 3 Ga 5 O 12 (GGG) crystals under irradiation with γ-quanta (E=1.25 MeV, D= 10 5 Gy ) as well as transient CC created in the crystals under irradiation with pulsed electron beam (E=0.25 MeV, pulse duration 10 ns, fluence 10 12 cm -2 , time interval of registration 0-500 ns). On the basis of the performed study of optical absorption spectra of the as-grown and irradiated crystals it was established the correlation between a defect subsystem of as-grown crystals and a type of CC induced by radiation in the crystals. The role of Ca 2+ dopant ions in the processes of CC formation is examined. Models of the stable and transient CC are proposed.
