在激光冲击强化（LSP）技术中，作为冲击载荷的驱动源头和能量来源，激光脉冲参数的不同选取决定着激光吸收机制取向、能量沉积程度乃至等离子爆炸行为规律的差异，进而对冲击载荷形态特征和材料表面强化效果产生重要的决定作用。本文对目前LSP技术中涉及的各类激光参数在激光驱动冲击效应中的作用机理、影响规律，以及在工艺配给上的研究和认知现状进行了综述。针对激光时域结构在决定等离子体膨爆行为和冲击载荷特征中的重要性，以及目前LSP普遍采用调Q激光器高斯时间波形的技术现状展开评述，并指出通过优化激光脉冲时域结构来提升光能向机械能的转换效率，或通过调节激光时域参数来实现精准操控冲击载荷特征具有可能性。

In laser shock processing (LSP) technology, as the driving source and energy source of shock loads, the different selection of laser pulse parameters determines the laser absorption mechanism, energy deposition, and even the plasma explosion behavior. This plays an important role in determining the morphological characteristics of shock loads and the surface strengthening effect of materials. This paper provides a review of the mechanisms and influencing laws of various laser parameters involved in LSP technology in laser driven shock effects, as well as the current research and cognitive status in process allocation. The importance of laser time profile in plasma explosion behavior and shock loading characteristics is reviewed, as well as the current status that Gaussian-like profiles that output from Q-switched laser is commonly used in LSP. It also points out that optimizing the laser time profile can improve the conversion efficiency of laser energy to mechanical energy. And it is possible that shock load characteristics can be accurately manipulated by adjusting laser time profiles.
