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.
