Cr^(3+):LiGaW_2O_8晶体的光谱研究

SPECTROSCOPY INVESTIGATION OF THE Cr^(3+)-DOPED LITHIUM GALLIUM TUNGSTATE CRYSTAL (Cr^(3+): LiGaW_2O_8)

研究了作者研制的Cr^(3+):LGT晶体的室温吸收和荧光光谱,用比较简捷的方法进行了能级、晶场强度和跃迁截面的计算分析,从光谱学观点可以认为这种晶体是一种较有潜力的终端声子可调谐激光材料。

The investigation of the room-temperature absorption and emission spectra of the Cr^(3+): LGT crystal, which was first proposed in the authors' laboratory, is reported. By means of a direct and simple method, the energy levels, crystal field strength and the transition cross-section are determined. It can be seen that this crystal is a kind of potential phonon-torminated infrared tunable laser material.
