Compact Transportable Optical Standard Based on a Single 171Yb+ Ion (“YBIS” Project)

Аннотация

The schematic diagram of the compact transportable optical frequency standard based on the quadrupole transition in a single ¹⁷¹Yb⁺ ion with a relative instability at the levelx of 5 · 10⁻¹⁶, less than 1m³ in volume and less than 300 kg in weight is presented. The ionic trap and laser systems are described. Trapping and laser cooling of the ¹⁷⁴Yb⁺ ion are experimentally demonstrated.
