Abstract

The narrow linewidth 674 nm /sup 2/S/sub 1/2/-/sup 2/D/sub 5/2/ transition in a cold Sr/sup +/ ion confined within an rf Paul trap has been probed using an optically-narrowed 674 nm diode laser, offset-locked to a second diode laser stabilised to a high finesse low-expansion reference cavity. A preliminary interferometric frequency measurement of the /sup 2/S/sub 1/2/-/sup 2/D/sub 5/2/ transition will be presented.<>
