This paper describes a control system that integrates the beam alignment subsystem and the parameter measurement subsystem of SGII-A facility based on Tango Controls. This is the first attempt to apply Tango Controls to the control system of a high-power laser facility. The new control system employs a hierarchical structure that consisting of a device layer, a task layer, and a GUI layer. Physical devices of both subsystems are developed into virtual device service software, acquiring data while hiding complex instructions from physical devices. Using the Tango soft bus, task applications collect data from the device layer, process the data, and send commands to control physical devices. By taking advantage of Tango's communication protocol, these applications can provide concurrent access. New client GUIs developed using QT and based on Tango’s unified interface are more convenient and intuitive
