The XingGuang III (XGIII) laser facility at the Science and Technology on Plasma Physics Laboratory at the Laser Fusion Research Center is unique in the world and consists of one 0.7 PW picosecond beam, one 0.6 PW femtosecond beam and one 1 kJ nanosecond laser beam. The three laser beams with different wavelengths and durations can converge in the target chamber with high spatial and temporal synchronization. Because of its smart beam configurations, XGIII providesunique opportunities for multi-beam pump–probe experiments in research fields such as high-energy density physics, plasma physics and laboratory astrophysics. Laser-driven high-energy particle beams were experimentally investigated, and found to play an important role in pump–probe schemes. High-energy electrons, protons, positrons and their experimental scalings were obtained using the picosecond laser beam with an intensity of 10 19 W cm −2 . A two-beam pump–probe experiment was demonstrated in whi...
