In this work, the absorption, fluorescence spectra, and fluorescence decay curve of Nd:Lu3Al5O12, i.e., neodymium lutetium aluminum garnet (Nd:LuAG) ceramic are investigated. A diode-end-pumped Nd:LuAG ceramic laser is demonstrated for the first time (to our knowledge). We present the experiment results of Nd:LuAG ceramic’s continuous wave (CW) and electro-optically (E-O) Q-switched performance. CW output power of 2.5 W is obtained, corresponding to optical-to-optical efficiency of 17.2% and slope efficiency of 24.3%. For the E-O Q-switched setup, the shortest pulse width and the largest pulse energy are measured to be 4.8 ns and 1.96 mJ, respectively. Its optical-to-optical efficiency and the slope efficiency are 17.3% and 28.7%, respectively.

传统的生物特征识别方法直接将用户的生物特征模板存储于数据库中。由于生物特征具有唯一性和稳定性,一旦被窃取,用户的生物特征将终身不可再用。针对此问题提出了一种存储伪生物特征图像的手掌静脉识别算法,该算法不从外部输入密钥,不存储原始掌脉生物特征模板。在注册阶段,于近红外光下采集用户手掌静脉图像,对图像进行加密形成伪图像,将伪图像存储于数据库中;在认证阶段,将数据库中的伪图像解密后提取特征,与认证阶段采
