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