摘　　要：应用倍频 Nd:YAG脉冲激光 ,在波长为 5 32 nm、脉冲宽度为 8ns的条件下 ,研究了金属团簇化合物WOS3Cu3I(2 - Me Py) 3的光限幅特性。其光限福特性优于富勒烯。Z- Scan研究结果表明 :该团簇具有自聚焦特性 。The optical limiting properties of the new metal cluster compound WOS 3Cul(2 Mepy) 3 was studied using frequency doubled, Q switched Nd:YAG laser with a 8 ns pulse at 532nm. The optical limiting performance of the cluster is better than that of Fullerene. The results measured with Z Scan technique show that the cluster exhibits a self focusing property, and the excited state absorption is the main mechanism of the optical limiting effect of the metal cluster compound.
