SummaryWe demonstrate 9.3-attosencond timing jitter [integrated from 10 kHz to 50 MHz offset frequency] optical pulse trains from 99 MHz repetition-rate mode-locked Ti:sapphire lasers. A phase discrimination signal is obtained using an optical heterodyne technique. The performance is the lowest timing jitter measured from any free-running mode-locked lasers and shows possibility of further suppression.
