激光热透镜效应是1964年Gordon等人首次报道的。他们在研究分子拉曼散射时发现了这一现象,并预言可用于测量溶液中痕量物质的微弱吸收。经过Fang、Swoffod、及Hu等人的努力,使得激光热透镜效应的理论得到了充实和发展,为其在分析领域中的应用打下了基础。1979年Dovichi和Harris首次发表了应用激光热透镜效应进行定量分析,用He-Ne激光为光源建立了单光束实验装置,对Cu-EDTA体系进行了测定。Imasaka等人于1980年采用双光束 The laser thermal lensing effect was first reported by Gordon et al. In 1964. They discovered this phenomenon when studying molecular Raman scattering and predicted that they could be used to measure weak absorption of trace substances in solution. Through the efforts of Fang, Swoffod, Hu and others, the theory of laser thermal lens effect has been enriched and developed, laying a foundation for its application in the field of analysis. In 1979, Dovichi and Harris first published a quantitative analysis using the laser thermal lens effect. A single-beam experimental apparatus was set up with He-Ne laser as the light source to measure the Cu-EDTA system. Imasaka et al. Used two beams in 1980
