More and more researchers have shown great interest in laser plasma shock wave application technology for its advantages such as energy-saving, efficient and controllable. Laser plasma shock wave effects were reviewed, and the effects of the target surface plasma and laser sustaining detonation on target impulse transfer were analyzed. The two technologies using laser plasma shock wave were discussed in detail, namely, laser peening technology and laser propulsion technology. By comparing the advantages of domestic and foreign technologies, the principle and application status of laser peening technology and laser propulsion technology were systematically investigated, and the trend of application research development of laser plasma shock wave effects was also analyzed. The mobile short-pulse high-energy laser will be an important research direction in the future. The effects of laser parameters, environment parameters and target material parameters on the laser plasma shock wave effects and acoustic effects generated by the interactions between laser and the target should be studied from the aspects of theory and experiment. And the relationship between laser plasma acoustic effects and laser plasma shock wave mechanical effects was explored. High-energy lasers have large volume, high environment requirements and low stability. In order to apply laser plasma shock wave effects in practice, short-pulse high-energy mobile lasers should be developed, to improve the mobility, convenience and reliability of laser plasma shock wave effects application systems.
