In view of the issue that the present domestic industrialization of laser shock peening equipment is not high, a laser shock peening equipment has been developed by using fixed optical system structure and modular design method. The design scheme of laser shock peening equipment, the characteristics of laser optical path arrangement and the system control method are analyzed, and the technical specifications of laser shock peen-ing equipment are tested. When the room temperature stables at (22 ± 2) ℃ and 20 minutes after the device is switched on, the technical parameters such as the maximum output single pulse energy up to 25 J, energy insta-bility < 3%, pulse width which can be continuously adjusted between 16 ns and 20 ns, pulse width instability < (-1 ns~1 ns), beam divergence < 2.5 mrad, beam points instability <50 μrad, the repetition rate of 0.5 Hz~5 Hz are achieved, the transmission efficiency of the optical system is about 92%, the thickness of the constraint layer is uniform and the flow rate is continuously controlled. The test results show that the performance of the laser shock peening equipment is good enough for industrial applications.
