摘　　要：本文采用在YAG晶体中共掺铒铈离子,利用Ce^(3+)离子具有f—d宽带吸收跃迁,提高Er^(3+)离子对泵浦能量的吸收,以降低YAG:Er,Ce晶体的激光阈值。并测定了晶体在室温下的吸收光谱和荧光光谱。讨论了YAG:Er^(3+),Ce^(3+)晶体的光谱特性。用Judd—Ofelt理论计算了晶体中Er^(3+)离子振子强度,并与单掺铒离子YAG:Er^(3+)晶体中的数值进行了比较。We report in this paper the spectral properties of YAG double doped with Er3+(2 at %),Ce3+(0. 3 at %) (YAG : Er, Ce) laser crystals grown by Czocharalski technique. The absorption and emission spectra have been measured at room temperature. By using absorption spectra and Judd-Ofelt theory the experimental oscillator strengths were calculated and discussed as well.
