Experimental demonstration of femtosecond two-color x-ray free-electron lasers.

چکیده
With an eye toward extending optical wave-mixing techniques to the x-ray regime, we present the first experimental demonstration of a two-color x-ray free-electron laser at the Linac Coherent Light Source. We combine the emittance-spoiler technique with a magnetic chicane in the undulator section to control the pulse duration and relative delay between two intense x-ray pulses and we use differently tuned canted pole undulators such that the two pulses have different wavelengths as well. Two schemes are shown to produce two-color soft x-ray pulses with a wavelength separation up to ∼1.9% and a controllable relative delay up to 40 fs.

متن کاملNanosecond pump–probe device for time-resolved serial femtosecond crystallography developed at SACLA
X-ray free-electron lasers (XFELs) have opened new opportunities for time-resolved X-ray crystallography. Here a nanosecond optical-pump XFEL-probe device developed for time-resolved serial femtosecond crystallography (TR-SFX) studies of photo-induced reactions in proteins at the SPring-8 Angstrom Compact free-electron LAser (SACLA) is reported. The optical-fiber-based system is a good choice f...
متن کاملA proposal for multi-tens of GW fully coherent femtosecond soft X-ray lasers
X-ray free-electron lasers delivering up to 1 X 10 coherent photons in femtosecond pulses are bringing about a revolution in X-ray science'. However, some plasma-based soft X-ray lasers are attractive because they spontaneously emit an even higher number of photons (1 X 10), but these are emitted in incoherent and long (hundreds of picoseconds) pulses as a consequence of the amplification of st...
متن کاملFemtosecond all-optical synchronization of an X-ray free-electron laser
Many advanced applications of X-ray free-electron lasers require pulse durations and time resolutions of only a few femtoseconds. To generate these pulses and to apply them in time-resolved experiments, synchronization techniques that can simultaneously lock all independent components, including all accelerator modules and all external optical lasers, to better than the delivered free-electron ...
