一、概述用红宝石激光对透明样品进行激光显微光谱分析时,常因样品透明度大,导致大部分激光能量透过样品,不能使样品蒸发,亦即不能引起激发发光。为了开展对透明矿物的激光显微分析工作,必须缩短激光脉冲时间,提高激光输出功率。我所曾用隐化菁染料胶片作Q开关,但是此种胶片失效期快,制备较复杂且有毒,效果不理想。1969年 KuLeumi、 Yoshino等人在实验中研究了叶绿素d作红宝石激光Q开
First, an overview of transparent laser ruby laser microscopy analysis of transparent samples, often due to the transparency of the sample, resulting in most of the laser energy through the sample, the sample can not be evaporated, that is, can not cause excitation of light. In order to carry out the laser microscopic analysis of transparent minerals, it is necessary to shorten the laser pulse time and improve the laser output power. I used to use a cyanine dye film as the Q switch, but the film expired quickly and the preparation was complicated and poisonous with unsatisfactory results. In 1969 KuLeumi, Yoshino et al. Studied chlorophyll d as ruby laser Q
