Preparation and laser performances of Nd3+:GSGG ceramic powder raw materials

摘要

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 Nd^3+ 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℃ for 4h, and the characterized fluorescence decay curves showed that about 1 at.% concentration of Nd^3+in Nd^3+:GSGG precursor presented optimum fluorescence intensity at 1.06μm waveband.
