Abstract
The color centers, which are generated in yttrium-aluminium perovskite YAP:Nd(1 at.%) and YAP:Er(50 at.%) crystals under the influence of ul traviolet and gamma-irradiation, have been studied by absorption spect roscopy. Both stable and transient at room temperature color centers a re generated. It is shown that the transient color centers are mainly responsible for the decrease of laser generation efficiency of Nd:YAP and YAP:Er irradiated crystals, although physical mechanisms leading t o efficiency decrease are different in these materials.
