AI Contract Overview

The contract pertains to the development of a cutting-edge synchronization technology for femtosecond lasers, specifically focusing on reducing the relative timing jitter between pulse trains from two independent mode-locked Ti:Sapphire oscillators. The invention achieves timing control with remarkable precision, utilizing a system of three interleaved phase locked loops that operate with successively finer timing resolutions. This approach maintains a full-scan dynamic range while minimizing timing jitter noise to below 15 femtoseconds over a period longer than one minute, a level of precision comparable to the pulse durations generated by the most advanced ultrashort pulse lasers. This technology offers an all-electronic method for controlling the timing offset between the two pulse trains, enhancing stability and repeatability compared to traditional mechanical systems. The synchronization system is versatile, capable of being applied to any mode-locked lasers, including those with differing repetition rates. The contract is managed under the Department of Commerce’s National Institute of Standards and Technology (NIST) office in Gaithersburg, Maryland, emphasizing advancements aligned with precision laser synchronization technologies.

Full Description

NIST DOCKET NUMBER: 01-010PA Title: Sub-15-femtosecond Active Synchronization Of Two Passively Mode-locked Ti: Sapphire Oscillators Description: The invention is able to control the relative timing jitter between pulse trains from two independent mode-locked femtosecond lasers to an unprecedented precision using three interleaved phase locked loops. The key technology is the implementation of phase locked loops with successively higher timing resolutions to effectively minimize the timing jitter while preserving the full-scan dynamic range. The timing jitter noise is below 15 femtoseconds, when observed with 1 kHz bandwidth over a period longer than one minute. This is comparable to the pulse duration generated from the state-of-art ultrashort pulse lasers. Control of timing offset between the two pulses, i.e. relatively tuning of one pulse train with respect to the other, is accomplished by all-electronic means, leading to a high degree of stability and repeatability compared to mechanical based systems. The technology can be applied to any mode-locked lasers, even with different repetition rates.
