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.
首次在低浓度掺钕钒酸盐晶体粉末中证明了室温随机激光作用。激光阈值和发射效率与化学计量比硼酸盐晶体粉末中获得的相当。本研究提供了掺钕钒酸盐粉末在光谱和时间域的随机激光特性的完整图景，以及一个解释随机激光最相关特征的简化模型。
