Structure and spectral properties of Nd3+-doped KBaGd(MoO4)3 crystal with a disorder structure

Abstract

In order to obtain new, more efficient laser materials for diode laser-pumped lasers, the laser host materials with broad absorption bands are very important. This paper reports the structure and spectral properties of Nd3+ : KBaGd(MoO4)3 crystal. KBaGd(MoO4)3 crystallizes in the monoclinic system with space groupC2/c. The structure analysis shows that KBaGd(MoO4)3 crystal has a disordered structure. The investigation of the spectral properties of Nd3+ : KBaGd(MoO4)3 crystals shows that it exhibits broad absorption and emission bands, which are caused by the disordered structure of the KBaGd(MoO4)3 crystal. The broad absorption band is very suitable for diode laser pumping. To sum up the spectral properties of Nd3+ : KBaGd(MoO4)3 crystal, it may be regarded as a potential solid-state laser material for diode laser pumping.
