Abstract: A beatnote between the Ca and Hg+ optical frequency standards via a mode-locked fs-laser frequency comb demonstrates the highest frequency stability measured to date. The high stability accelerates evaluation of the Ca standard's systematic shifts. ©2005 Optical Society ofAmerica OCIS Codes: (120.3940) Metrology; (300.6320) High-resolution spectroscopy; (140.3320) Laser coolin
