N2 - Standard methods of laser cooling 171Yb+ in a radiofrequency trap involve the use of coherent optical fields resonant to the optical transition of the 2 S 1/2 → 2 P 1/2 line, as well as a magnetic field that is used to destroy the coherent population trapping (CPT) appeared at the 2 S 1/2(F = 1) level. Further precision measurements with use of the clock transitions (quadrupole 2 S 1/2(F = 0) → 2 D 3/2(F = 2) and octupole 2 S 1/2(F = 0) → 2 F 7/2(F = 2)) require significant suppression and control of residual magnetic fields. In this work, we investigate in detail an alternative method of laser cooling 171Yb+ with use of polychromatic fields, which allows completely eliminate the use of a magnetic field in the ion cooling process and thus suppress Zeeman quadratic shift associated with uncontrolled residual magnetic fields.
