一、概况六十年代初,激光器问世后不久,人们就利用激光具有高亮度的特点,进行材料加工。经过多年的研究与应用实践,激光热加工技术的应用范围越来越广(见表1),激光已成为一种特殊的加工工具。 I. Overview In the early 1960s, shortly after the advent of lasers, people took advantage of the high brightness of the laser for material processing. After years of research and practice, the application of laser thermal processing technology is more and more widely (see Table 1). Laser has become a special processing tool.
