摘　　要：本文综述了脉冲激光辐照形成折射率改变、激光烧蚀产生表面周期结构和表面多孔结构以及激光块体材料微加工等几个方面的研究进展,总结了高分子材料的激光改性和烧蚀机制以及激光脉冲宽度和波长的影响,而激光作用机理还没有一个完善的表述.通常,对于不同的高分子材料,一般表现为光热和光化学特性共存的混合机制,并且与材料的结构和特性紧密相关.通过分析脉冲激光高分子材料微加工的特性,展望了脉冲激光在高分子材料微加工领域的应用前景.This paper summarizes the research progress of laser induced refractive index modification, surface periodic structures and porous structures produced by laser ablation, and laser micromachining in bulk materials. The mechanisms of laser polymer modification and ablation, and the effects of laser wave- length and pulse duration are discussed. The mechanisms of laser ablation are not clear yet. Generally, the mechanism is a mixture of photochemical and photothermal features and is closely related to the poly- mer structure and properties. Through analysis of the characteristics of laser processed polymer materials, the application prospect of laser micromachining of polymer materials is explored.
