摘要：
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.
