Abstract
The optical transmission (OT) spectra of Yb:LaSc3(BO3)4 and Yb:LuYSiO5 laser crystals have been analyzed before and after irradiation from a 60Co source with doses up to 45 Mrad. The OT spectra of the Yb:LuYSiO5 crystal are found to be the same (within the measurement error) before and after irradiation. The irradiation of the 10 at.%Yb:LaSc3(BO3)4 crystal significantly changes its OT spectra in a wide spectral range (330 to 700 nm). A 975-nm laser based on a previously irradiated 4 at.%Yb:LuYSiO5 crystal has exhibited a differential efficiency of 23% under diode pumping. The up-conversion luminescence spectra in the visible range of the crystals under study have been explained.
