一、引言自从1960年出现了激光以来,已有二千多种波长的激光器实现了振荡,把激光应用到各个领域的研究也在不断地进行。1962年在刀片上用红宝石激光器钻孔的试验开始了激光在加工方面的研究。迄今激光已在加工方面得到广泛应用,大的类别有:激光钻孔,激光切割,激光焊接,激光热处理等。其中很多已被应用于工业生产中。单就激光钻孔,应用就是多种多样的,不少已达到了实用化。近年来这一技术巳发展 I. INTRODUCTION Since the emergence of the laser in 1960, more than 2000 kinds of lasers have been oscillated, and the research on the application of laser in various fields is also constantly carried out. The 1962 experiment of drilling a hole with a ruby ​​laser on a blade began a laser processing study. So far the laser has been widely used in processing, the major categories are: laser drilling, laser cutting, laser welding, laser heat treatment. Many of these have been used in industrial production. Laser drilling alone, the application is varied, many have reached the practical. This technology has been developed in recent years
