Two-color FEL amplifier for femtosecond-resolution pump-probe experiments with GW-scale X-ray and optical pulses
Pump-probe experiments combining pulses from a X-ray FEL and an optical femtosecond laser are very attractive for sub-picosecond time-resolved studies. Since the synchronization between the two independent light sources to an accuracy of 100 fs is not yet solved, it is proposed to derive both femtosecond radiation pulses from the same electron bunch but from two insertion devices. This eliminat...
متن کاملDelay control in attosecond pump-probe experiments.
The time delay between the pump and probe pulses in attosecond time-resolved experiments, such as attosecond streaking, is commonly introduced by splitting and recombining the two pulses in an interferometer. This technique suffers from instability in the optical path lengths of the two arms due to mechanical vibration of the optical elements and fluctuating environmental conditions. We present...
متن کاملTHz pulse doubler at FLASH: double pulses for pump–probe experiments at X-ray FELs
FLASH, the X-ray free-electron laser in Hamburg, Germany, employs a narrowband high-field accelerator THz source for unique THz pump X-ray probe experiments. However, the large difference in optical paths of the THz and X-ray beamlines prevents utilization of the machine's full potential (e.g. extreme pulse energies in the soft X-ray range). To solve this issue, lasing of double electron bunche...
متن کاملShot-noise-limited detection of absorbance changes induced by subpicojoule laser pulses in optical pump-probe experiments
The optical pump-probe technique is a widely used method in ultrafast spectroscopy.’ A pump pulse initiates optical changes in the sample, and a subsequent probe pulse monitors the changes at variable time delay. Current modelocked Ti:sapphire lasers can provide ultrashort pulses with energies of up to 25 nJ at repetition rate 100 MHz (-2.5 W of cw power); such pulses may cause absorbance chang...
