Abstract

Abstract:

This paper explores a new laser working material: gallium scandium gadolinium (GSGG), which was successfully prepared by one step co-precipitation method, and the potential properties of this Nd³⁺ doped laser ceramic raw materials were proposed. The size of the prepared powder was uniform and mainly about 65 nm. The GSGG phase could be obtained after a heat-treatment of 1000?°C for 4 h, and the characterized fluorescence decay curves showed that about 1 at.% concentration of Nd³⁺ in Nd³⁺:GSGG precursor presented optimum fluorescence intensity at 1.06 μm waveband.

Key words: Nd³⁺:GSGG, One step co-precipitation, Laser properties
