Abstract

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.

Ce:Nd:YAG侧泵浦太阳能激光器

摘要本文报道了采用侧泵浦结构在Ce:Nd:YAG太阳能激光器性能方面取得的重大进展。采用双级半球面透镜和梯形抽运腔组成的太阳激光头，将抛物面镜聚焦区的太阳集中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Nd:YAG激光棒的激光输出性能进行了比较。在入射太阳能功率为600 W时，Ce:Nd:YAG太阳能激光器的收集效率为23.6 W / m2，斜率效率为4.4%，太阳-激光功率转换效率为2.8%，分别是Nd:YAG棒的1.57倍、1.47倍和1.56倍。Ce:Nd:YAG侧泵浦太阳能激光器的收集效率和太阳-激光功率转换效率分别比之前记录的Nd:YAG侧泵浦太阳能激光器提高了1.39倍和1.15倍。我们证明了Ce:Nd:YAG陶瓷棒作为侧泵浦太阳能激光器增益介质的巨大潜力。
