Abstract

With the implementation of a bandwidth servo, along with improved laser construction and associated better passive stability, we have achieved sub-femtosecond relative timing jitter between two independent, actively synchronized, mode-locked Ti-sapphire lasers. A timing jitter of 0.58 fs is obtained with a 160-Hz observation bandwidth over several seconds. Within a 2 MHz observation bandwidth, the timing jitter is 1.75 fs. Excellent repeatability and rapid speed in setting an arbitrary time delay between two pulses are also demonstrated.
