Abstract

As came out in one of our past experiments concerning the Pr:YAlO₃ (Pr:YAP) active material, UV-radiation had an adverse effect for lasing action due to the crystal solarization. So, co-doping of this material by Ce³⁺-ions having broad absorption-bands in the UV-region has been proposed for crystal property improvement in terms of color-center formation. The Pr,Ce:YAP absorption-spectrum investigation under UV-radiation exposure, in comparison to the Pr:YAP one, is reported in this contribution. Moreover, lasing properties of these two materials under the GaN-diode pumping are summarized.
