中性镱（YbI）和单离子化镱（YbII）被广泛应用于量子光学、计量学和量子信息科学的实验中。我们报告的调查同位素选择性的双光子电离的镱，允许有效加载的离子阱与镱。结果提出了两种颜色（399 nm和369 nm）和单色（399 nm）的光电离和它们的效率相比，电子碰撞电离。几乎确定性加载到一个线性保罗陷阱的所需数量的Yb II离子。第一个结果已经在量子信息的上下文中给出（Balzer等人，Phys.Rev.A73：041407（R），2006），并且本论文旨在给出光电离和离子阱加载过程的详细描述和理解。此外，我们提供了有用的技术细节的生产和表征合适的原子炉。
Neutral ytterbium (YbI) and singly ionized ytterbium (YbII) are widely used in experiments in quantum optics, metrology, and quantum information science. We report on the investigation of isotope-selective two-photon ionization of YbI that allows for efficient loading of ion traps with YbII. Results are presented on two-color (399 nm and 369 nm) and single-color (399 nm) photoionization and their efficiency is compared to electron impact ionization. Nearly deterministic loading of a desired number of YbII ions into a linear Paul trap is demonstrated. First results have been presented in the context of quantum information (Balzer et al. in Phys. Rev. A 73:041407(R), 2006), and the present paper is intended to give a detailed description and understanding of the photoionization and ion trap loading processes. Furthermore, we provide useful technical details of the production and characterization of suitable atomic ovens.
