前言 自1960年MAIMAN发明红宝石激光器之后,人们很快意识到高功率的激光器能用于蒸发少量固体物质,而激光蒸气云发出的辐射,无论是否采用辅助激发,均能观察到分析光谱。激光作为蒸发固体样品的一种手段,很早就与火花发射法联合,应用于各种样品的微区分析;随后又应用于固 Foreword Since MAIMAN invented ruby ​​lasers in 1960, it was quickly realized that high power lasers could be used to evaporate a small amount of solid matter, whereas the radiation emitted by laser vapor clouds, whether or not assisted by excitation, was observed in the analytical spectrum. Laser as a means of evaporating solid samples, has long been associated with the spark emission method, applied to a variety of sample micro-area analysis; and then applied to the solid
