Research Abstract

Solar-pumped laser system is enhanced by developing a new solar light cavity. A 3^<rd> concentrator of solar power is adapted to the previous 2^<nd> solar concentrator. This 3^<rd> concentrator is newly developed and 120W of stable output is realized although laser medium was broken and stable laser output was impossible in previous study. 30 W/m^2 of efficiency is realized because of this study. This is the new world record which is 1. 5 times larger than previous record of efficiency of solar-pumped laser system.
