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 ultraviolet and γ-irradiation, have been studied by absorption spectroscopy. Both stable and transient at room temperature color centers are 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 to efficiency decrease are different in these materials.
