Laser based timing and seeding of free electron lasers witth high harmonics

Advances in femtosecond laser technology provide large scale, long term stable, timing distribution, rf-synchronization as well as synchronization of multiple pulsed laser sources on a femtosecond time scale. Experimental results demonstrating 0.3 fs synchronization of independently mode-locked lasers, measured of broad bandwidth, is presented.  This opens up the possibility to generate fully coherent femtosecond x-ray sources by seeding with short wavelength high harmonics. Possible fiber laser based systems for reliable laser drivers for photo injection and high-harmonic generation are discussed.Grail"
