Engineering closed optical transitions in rare-earth ion crystals

Bartholomew, John; Ahlefeldt, Rose; Sellars, Matthew


We propose a protocol to preserve the spin state of rare-earth ions when they are optically cycled. This technique uses large magnetic fields to increase the probability of an optically excited ion returning to its initial spin state. This Zeeman enhanced cyclicity is shown to be applicable to non-Kramers ions in various crystals irrespective of the site symmetry. The specific example of Pr3+:Y2SiO5 is investigated to demonstrate that the protocol can create closed optical transitions even...[Show more]
