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.
