摘要

针对NINT3000质谱计的结构特点

利用高斯光学理论

推导出双透镜系统光学参数传递方程

并以此为依据设计出一套光学系统和光路调整装置

实现了激光束在离子源腔内的精确定位和聚集

焦斑半径为160μm

调节精度为10μm。目前

该系统已经安装在激光共振电离质谱计上

并实现了镥的单色双光子共振电离。

Abstract

An equation has been established for the transmission of optical parameters in a two-lens system using the Gaussian optical theory

and in the light of the structural features of NINT3000 laser resonance ionization mass spectrometer

an optical system and a laser path adjustment device were then designed using the above equation to achieve precise location and focusing of laser beam in the ion source cavity. The radius of the laser focal spot is 160 μm

and the adjusting precision being 10 μm. The system has now been installed in the laser resonance ionization mass spectrometer

and the homochromatic two-photon resonance ionizations of lutetium has been realized.
