Space solar energy flux density, from the day and night climate impact, it can be used directly or indirectly-pumped solid state lasers. The use of indirect-pumped solid-state lasers, sunlight to laser energy conversion process are more and less efficient. Directly pumped, in the absence of intermediate links, and thus sunlight to laser conversion efficiency is high, and has a simple structure, good reliability. Therefore, direct sunlight the pump to achieve the conversion of sunlight into laser is potentially important.This paper introduces the main characteristics and prospects of sunlight directly pumped Nd: YAG laser. The characteristics of the Nd: YAG laser crystal nature, space, sunlight radiation introduced sunlight through 5800k blackbody radiation simulation of Nd: YAG laser crystal absorption spectra and the matching of the solar spectrum were analyzed theoretically proved that the Nd: YAG as the feasibility of direct solar-pumped laser material.
