April 7, 2002 (on February 25), Imo, 'SG II giant lasers successfully developed.

2002, "SG II giant lasers successfully developed. The advent of "SG II, marking the high power laser research and laser fusion research has been advanced in the world. At present, such a giant laser precision that only a few countries such as the United States, Japan construction. "SG II overall technical performance has entered the world's top five.
built in Shanghai Institute of Optics and Fine Mechanics, "SG II", hundreds of optical devices for integration in the size of a football field empty.
room. 8 beam of intense laser three-dimensional arrangement of the amplification chain gathered in a small fuel target ball through space, equivalent to the global grid power sum of the multiples of the powerful power emitted within a nanosecond ultrashort instant , thus releasing the extreme pressure and high temperatures to trigger a fusion reaction.
