Laser ablation loading of a radiofrequency ion trap
K. Zimmermann, M. V. Okhapkin, O. A. Herrera-Sancho +1
The production of ions via laser ablation for the loading of radiofrequency (RF) ion traps is investigated using a nitrogen laser with a maximum pulse energy of 0.17 mJ and a peak…
High-accuracy optical clock based on the octupole transition in 171Yb+
N. Huntemann, M. Okhapkin, B. Lipphardt +3
We experimentally investigate an optical frequency standard based on the 467 nm (642 THz) electric-octupole reference transition 2S1/2(F=0) -> F7/2(F=3) in a single trapped 171Yb+…
Atomic clocks with suppressed blackbody radiation shift
V. I. Yudin, A. V. Taichenachev, M. V. Okhapkin +6
We develop a nonstandard concept of atomic clocks where the blackbody radiation shift (BBRS) and its temperature fluctuations can be dramatically suppressed (by one to three orders…
