1960年红宝石激光器问世后不久,激光加工方案就被提出,而且在各研究所进行了实用化试验。但是,几年前,用于激光加工的激光器,主要是脉冲振荡的红宝石激光器和钕玻璃激光器,在重复加工方面花费时间,加工对象只限于各种材料打孔和薄金属材料的点焊 Shortly after the Ruby laser was introduced in 1960, the laser machining program was proposed and practical tests were conducted in various institutes. However, a few years ago lasers used for laser processing, mainly pulsed oscillating ruby ​​lasers and neodymium glass lasers, took time to duplicate machining and were restricted to the drilling of various materials and spot welding of thin metal materials
