Inertial Fusion Energy (IFE) is potentially a promising scheme for the energy sustainable development, and also a platform for the studies of high energy density physics. However, achieving pure fusion in the laboratory still faces difficult challenges. National Laboratory on High Power Laser and Physics (NLHPLP) in Shanghai Institute of Optics and Fine Mechanics (SIOM), Chinese Academy of Sciences (CAS) has built up a serious of successful user facilities named SG-II high power laser facilities, which provided a high degree of experimental flexibility at one site with a diverse set of a lasers, to push forward researches on pathways to Inertial Fusion Energy.SG-II high power laser facility, with a picosecond and a femtosecond PW lasers and 16 beams nanosecond laser, has extraordinary output performance for ICF research and high energy density science (HEDS). Experimental shots for different kinds of researches are provided to domestic and international users since 1990s.Also, some key technologies have been developed to improve the performance to the facility. Some efforts on increasing the small gain coefficient were made to increase the energy of 1\omega output. The other efforts such as raising the load ability of 3\omega, enhancing beam quality, and improving the beam focusing ability and beam direction of ps pulse were also conducted.
