一、概述 自一九六○年制成红宝石激光器以后,激光技术于一九六二年首次在地质上得到应用。它作为一种崭新的光谱分析光源——激光光源,引起人们的重视。十多年来,人们卓有成效地利用了激光的单色性、方向性和能量密度高的特点,把激光束聚焦到样品上,使其蒸发气化,用摄谱仪或光电记录等方法,进行激光光谱(国外叫激光微探针)微区分析。欧美等国在最近几年先后生产了激光微区分析商品仪器; I. Overview Since the ruby ​​laser was made in 1960, laser technology was first applied in geology in 1962. As a new spectroscopy light source - laser light source, it attracts people’s attention. For more than a decade, people have made effective use of the monochromatic, directional and high energy density characteristics of a laser beam to focus the laser beam on a sample, evaporate and gasify it, and perform spectroscopic or optical recording Laser spectroscopy (foreign called laser microprobe) micro-area analysis. In recent years, Europe and the United States and other countries have produced a laser micro-analysis of commodity equipment;
