Three-Dimensional Paul Trap with High Secular Frequency for Compact Optical Clock

Abstract

The Paul ion trap is developed for the use in a compact frequency standard based on a single ytterbium ion. The design features are the use of atomic ovens for compensating for parasitic electric fields and good optical accessibility. The results on trapping and laser cooling of a single ¹⁷¹Yb+ ion are presented. A secular frequency of up to 1.2 MHz has been achieved.
