Reducing decoherence in optical and spin transitions in rare-earth-metal-ion-doped materials

McAuslan, D. L.; Bartholomew, John; Sellars, Matthew; Longdell, Jevon Joseph


In many important situations, the dominant dephasing mechanism in cryogenic rare-earth-metal-ion-doped systems is due to magnetic field fluctuations from spins in the host crystal. Operating at a magnetic field where a transition has a zero first-order Zeeman (ZEFOZ) shift can greatly reduce this dephasing. Here we identify the location of transitions with a zero first-order Zeeman shift for optical transitions in Pr3+:YAG and for spin transitions in Er3+:Y2SiO5. The long coherence times that...[Show more]
