自从工业激光器用于材料加工以来,实业家的乐观预言首次受到物质支持。在美国,被会见的国内外制造商和用户,都认为这种工业目前正在健康、茁壮、迅速地成长。乐观的理由是什么呢?第一,与其他重要设备的营业部门(如机床工业)相比,激光工业经受了80年代初期两年投资的严重削减,而机床工业却是严重的衰退。第二,激光技术已达到用户可以接受的水平,这是制造商们所长期期待的。第三,,最近特别重要的公 Industrial lasers have been materially supported for the first time since industrial lasers were used for material processing. In the United States, both domestic and foreign manufacturers and users interviewed think that this industry is currently growing healthily, robustly, and rapidly. What are the reasons for optimism? First, compared with other key equipment business sectors (such as the machine tool industry), the laser industry experienced a severe reduction in two years of investment in the early 1980s, and the machine tool industry is a serious recession. Second, laser technology has reached a level acceptable to users, which manufacturers have long expected. Third, the most important public
