首次在低浓度掺钕钒酸盐晶体粉末中发现了室温随机激光作用。激光阈值和发射效率与化学计量比的硼酸盐晶体粉末相当。本研究从光谱和时间两个方面完整地描述了掺钕钒酸盐粉的随机激光特性，并给出了一个与随机激光特性最相关的简化模型。(C)2011年美国光学学会
Room temperature random lasing action is demonstrated for the first time in a low concentrated neodymium doped vanadate crystal powder. Laser threshold and emission efficiency are comparable to the ones obtained in stoichiometric borate crystal powders. The present investigation provides a complete picture of the random lasing characteristics of Nd-doped vanadate powder both in the spectral and temporal domain, together with a simplified model which accounts for the most relevant features of the random laser.
