以Na2MoO4为助熔剂，用助熔剂提拉方法生长了掺Er3+的CaMoO4激光晶体，测试了晶体的光学均匀性，研究了晶体的光谱性能，并对其吸收光谱和荧光光谱进行了分析。晶体在981 nm处的吸收截面为0.6×10-20 cm2，在1538 nm处的发射截面为0.91×10-20 cm2。Er3+CaMoO4晶体可产生上转换荧光，在980 nm激发下可辐射峰值波长为532 nm和553 nm的绿光及670 nm的红光。光谱分析结果表明，Er3+CaMoO4晶体可能成为潜在的1.5 μm波段激光材料和上转换发光材料。

Er3+CaMoO4 crystal is grown by CZ (Czochralski) method from a flux of Na2MoO4. The optical homogeneity, absorption and emission spectra of Er3+CaMoO4 crystal are investigated. The absorption cross-section is 0.6×10-20 cm2 at 981 nm, and the emission cross-section is 0.91×10-20 cm2 at 1538 nm. 532 nm and 553 nm green up-conversion emission and 670 nm red up-conversion emission are observed at the 980 nm excitation. Er3+CaMoO4 crystal may be a potential 1.5 μm laser gain material and up-conversion luminescent material.
