Optically phase-locked femtosecond laser oscillator for precise synchronization with femtosecond x-ray beams

Our recent developments are described regarding a novel synchronization architecture based on all optical method to achieve precise timing synchronization in a large and complex X-ray beam system. There are several key technologies in this approach, and the recent achievement is a precise synchronization of two independent mode-locked Ti:sapphire laser oscillators with an optical phase-locked loop. The cross correlation of two femtosecond lasers was measured for the relative timing jitter as small as 28 fs.
