This paper describes a laser probing system for wire array Z-pinches established on Qiangguang facilityincluding design of the laser optical systemthe improvement on the quality of the laser sourceand the synchronizer triggering system for laser source and the facility.The system has been applied in Z-pinch experiments of aluminum and tungsten pla-nar wire arrays.The experimental results show that the typical characteristics of Z-pinch loads in different phase can be exactly recorded by the laser probing systemsuch as the non-uniform erosion of the wiresthe quasi-periodic modulation structure with submilimeter scale wavelengththe instability during the implosionand the tail mass distribution in the stagna-tion.The further research and improvements should be carried out on the triggering systemrecording system and quantitative analysis of the streak.
