抽象的。报道了采用侧面泵浦结构的Ce：Nd：YAG太阳激光器性能的重大进展。太阳能激光头由两级半球面透镜和梯形泵浦腔组成，将来自抛物面反射镜焦区的集中太阳辐射耦合并重新分配到激光棒中。测试了直径为4.0 mm、长度为35 mm的Ce：Nd：YAG激光棒的激光输出性能，并与相同尺寸的激光棒的激光输出性能进行了比较。在入射功率为600W时，Ce：NdYAG光激光器的收集效率为23.6W / m2，斜效率为4.4%，光-光转换效率为2.8%，分别是NdYAG棒的1.57倍、1.47倍和1.56倍。Ce：Nd：YAG侧面泵浦的太阳能激光器的收集效率和光-光转换效率分别是以前的记录的1.39倍和1.15倍。我们展示了Ce：Nd：YAG陶瓷棒作为侧面泵浦太阳能激光器的增益介质的巨大潜力。
Abstract. A significant advancement in the Ce:Nd:YAG solar laser performance using a side-pumping configuration is reported. A solar laser head was composed of a double-stage semispherical lens and a trapezoidal-shaped pumping cavity, which coupled and redistributed the concentrated solar radiation from the focal zone of a parabolic mirror into a laser rod. The laser output performance of a 4.0-mm diameter, 35-mm length Ce:Nd:YAG laser rod was tested and compared with that from a Nd:YAG rod with the same dimensions. At an incoming solar power of 600 W, the Ce:Nd:YAG solar laser achieved 23.6-W / m2 collection efficiency, 4.4% slope efficiency, and 2.8% solar-to-laser power conversion efficiency, which are 1.57, 1.47, and 1.56 times, respectively, higher than the ones obtained with the Nd:YAG rod. The Ce:Nd:YAG side-pumped solar laser has also 1.39 and 1.15 times more collection efficiency and solar-to-laser power conversion efficiency, respectively, than the previous record by Nd:YAG side-pumped solar laser. We demonstrate the great potential of the Ce:Nd:YAG ceramic rod as a gain medium for side-pumped solar lasers.
