据我们所知，这里报道了 Ce:Nd:YAG 太阳能泵浦激光器的首次发射。太阳能激光头由熔融石英液体光导透镜和锥形泵浦腔组成，它将来自抛物面镜焦区的集中太阳辐射耦合并重新分布到Ce:Nd:YAG激光棒中。将直径 5 mm、长度 30 mm Ce:Nd:YAG 激光棒与直径 5 mm、长度 30 mm Nd:YAG 激光棒的激光输出性能进行比较。 Ce:Nd:YAG太阳能激光器的太阳能泵浦功率为569 W，在1064nm处发射6 W连续波功率，对应的收集效率为4.9 W/m2。尽管该功率水平低于使用 Nd:YAG 棒获得的 10 W，但 Ce:Nd:YAG 激光介质可能是太阳能泵浦激光器的替代活性介质。
The first emission of a Ce:Nd:YAG solar-pumped laser is reported here, to the best of our knowledge. A solar laser head was composed of a fused silica liquid light guide lens and a conical pump cavity, which coupled and redistributed the concentrated solar radiation from the focal zone of a parabolic mirror into a Ce:Nd:YAG laser rod. The laser output performance of the 5 mm diameter, 30 mm length Ce:Nd:YAG laser rod was compared with that from a 5 mm diameter, 30 mm length Nd:YAG rod. With a solar pump power of 569 W, the Ce:Nd:YAG solar laser emitted 6 W continuous-wave power at 1064nm, corresponding to a collection efficiency of 4.9 W/m2. Even though this power level was lower than the 10 W obtained by using the Nd:YAG rod, the Ce:Nd:YAG laser medium may be an alternative active medium for solar-pumped lasers.
