摘　　要：激光打孔技术是最早实现工业应用的激光加工技术,先进的激光打孔技术在航空航天领域、燃气轮机等现代制造业中扮演着越来越重要的角色,本文从打孔技术的背景需求、加工方式、面临的重大学科问题和国外发展现状等方面对激光打孔技术进行梳理总结。与国际上先进的激光打孔技术和打孔设备相比,作为先进加工技术之一的激光打孔技术在国内还处于跟踪和基础研究局面,不过随着国内科研人员的不断努力,其发展对于我们而言既是机遇也是挑战,未来前景是明亮广阔的。Laser drilling is the first applicable technique of the laser processing industrial applications technology. The advanced laser drilling is playing an increasingly important role in the modern manufacturing, especially aerospace and gas turbine fields. In this paper, we give a simple summarization about laser drilling from the demand of the background, processing methods, the current situation and the development of foreign countries. Compared with the international advanced laser drilling technology and equipment, the laser drilling is still in the basic research and the tracking situation in China, as one of the advanced technologies; but with the continuous study by the domestic scientists, the development of the laser drilling technology is an opportunities and challenges for us in the future.
