Abstract
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 isotopeselective twophoton ionization of YbI that allows for efficient loading of ion traps with YbII Results are presented on twocolor 399 nm and 369 nm and singlecolor 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 73041407R 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
