dc.description.abstractIn this paper, we report a numerical study of high power Nd:YAG solar laser approach pumped through off-axis parabolic concentrators. Six off-axis parabolic mirrors with 15 m² total collection area were used to collect and focus the solar energy towards six 2V-shaped pump cavities, within which a 120 mm length, 7.5 mm diameter Nd:YAG laser crystal was transversally pumped. Six fused-silica lenses were also employed to efficiently couple the concentrated solar power with a laser rod. All pumping parameters of the laser design were optimized using the ZEMAX© non sequential ray-tracing method. The laser resonant cavity and its performance were analyzed by LASCAD© software. A maximum continuous-wave 1064 nm laser power of 646 W was numerically achieved in the multimode operation with high collection efficiency of 43.06 W/mm² and very small beam spot size. To the best of our knowledge, this is the highest laser output power from a single beam/single rod Nd:YAG solar laser scheme, which is more than 5 times that of the previous most powerful Nd:YAG solar laser. Moreover, the laser intensity at the focal plane was 2.85x106 W/cm2, which can produce magnesium energy more than 14 times over the existing experimental works for laser-induced magnesium production.en
