SG-II Laser Facility: 8-Beam System：
SG-II High Power Laser Experimental System (SG-II 8-Beam System) was started building in May 1994, complimented in 2000 and began operation in the same year. Adopting self-devoloped multi-aperture amplifiers and advanced in-line multi-pass laser amplification technology, SG-II 8-Beam System delivers laser beams with highest output energy of 6KJ/1ns and can operate at both the 2ed and the 3rd harmonic frequencies. The system has become one of the most important platforms of domestic experiments in frontier scientific areas such as ICF，X-ray and high energy density now and in faraway future.
