Details to come in a forthcoming paper.\u00a0 But, in brief:\u00a0we use a fiber EOM to span the isotope shift in some pairing of co-trapped calcium isotopes and scan the laser across the 729 nm transition in both ions simultaneously.\u00a0 This gives rise to a pair of spectra; we actually alternate scans across two transitions with opposing magnetic field sensitivities (yielding the four spectra shown).<\/p>\n

Fitting for the line-centers allows us to extract a value for the isotope shift which is independent from differential Zeeman shifts between the co-trapped ions.<\/p>\n
