综述了德日五大激光技术研究中心有关激光材料加工研究方面的新进展。德国的两大研究所分别是夫琅和费激光技术研究所（ILT）和辐射工具研究所。他们在激光加工系统实时监控和多激光器、多工作站集成制造技术方面处于领先地位。同时他们的工作也涉及到激光焊接、切割、烧蚀、表面技术、微加工等各个领域。而日本的有关研究工作主要有大阪大学、应用工程中心和先进材料加工研究中心承担。他们的研究工作侧重于激光加工的物理本质，数学模型的研究。

The new research and development on laser material processing technology are reviewed in this paper. In German,activities on laser material processing are mainly conducted in Fraunhofer-Institut fur Lasertechnik (ILT) and Institut fur Strahlwerkzeuge (IFSW). They are advancing in on-line process control and laser integrated production with several lasers and workstations. They also engaged in laser welding,cutting, ablation,surface technology and microprocessing. In Japan, research on laser material processing are mainly carried out in Osaka University, Applied Engineering Center (ALEC) and Advanced Materials Processing Institute. They concentrated their research projects on physical fundamentals and mathematical modeling of laser material interaction.
