系统研究了Nd：SrLaAlO 4（Nd：SLA）晶体的热学和光谱性质，包括热扩散系数、热膨胀系数、比热、热导率、偏振吸收光谱和偏振发射光谱。连续波（CW）和被动调Q Nd：SLA激光器的操作进行了研究。在1.077 μm波长处获得了3.54 W的最大连续光输出，光-光转换效率为46.4%。在被动调Q制度，最大平均功率，脉冲重复频率，和最短脉冲宽度分别为1.8 W，113 kHz，和12.6 ns。结果表明，Nd：SLA晶体是一种高效的激光增益介质。
The thermal and spectral properties of a Nd:SrLaAlO4(Nd:SLA) crystal were systematically studied, including thermal diffusivity, thermal expansion, specific heat, thermal conductivity, polarized absorption and emission spectra. Both continuous-wave (CW) and passively Q-switched Nd:SLA laser operations were investigated. The maximum CW output power of 3.54 W was obtained at 1.077 μm, corresponding to an optical-to-optical efficiency of 46.4%. In the passively Q-switched regime, the maximum average power, pulse repetition rate, and shortest pulse width were 1.8 W, 113 kHz, and 12.6 ns, respectively. All the results indicate that the Nd:SLA crystal is a highly efficient gain medium for laser applications.
