On April 7, 2002 (February 25, 2002 in the lunar calendar), China's "Shenguang-2" giant laser was successfully developed. On April 7, 2002, China's "Shenguang-2" giant laser was successfully developed. The advent of "Shenguang-2" marks that China's high-power laser scientific research and laser nuclear fusion research have entered the world's advanced ranks. At present, only a few countries such as the United States and Japan can build such sophisticated giant lasers. The overall technical performance of "Shenguang-2" has ranked among the top 5 in the world. The "Shenguang-2" built at the Shanghai Institute of Optics and Mechanics, Chinese Academy of Sciences, has hundreds of optical equipment integrated into an empty space the size of a football field. Inside. When eight powerful lasers are gathered to a small fuel target ball through a three-dimensional amplification chain, they can emit powerful power that is several times the total power of the global power grid in an ultra-short instant of one-billionth of a second., thereby releasing extreme pressures and high temperatures and triggering fusion reactions.
