Clocking femtosecond X rays.

چکیده
Linear-accelerator-based sources will revolutionize ultrafast x-ray science due to their unprecedented brightness and short pulse duration. However, time-resolved studies at the resolution of the x-ray pulse duration are hampered by the inability to precisely synchronize an external laser to the accelerator. At the Sub-Picosecond Pulse Source at the Stanford Linear-Accelerator Center we solved this problem by measuring the arrival time of each high energy electron bunch with electro-optic sampling. This measurement indirectly determined the arrival time of each x-ray pulse relative to an external pump laser pulse with a time resolution of better than 60 fs rms.

Femtosecond Electron and X-ray Generation by Laser and Plasma-based Sources
The generation of ultra-short x-rays by Thomson scattering intense laser pulses from electron beams is discussed, including recent experimental results and methods for enhancing the x-ray flux. A high flux of x-rays in a femtosecond pulse requires the generation of femtosecond electron bunches and a head-on Thomson scattering geometry. The generation of ultrashort electron bunches in a plasmaba...
متن کاملMev X rays and photoneutrons from femtosecond laser-produced plasmas.
We demonstrate a novel method to monitor the total angular distribution of the spectrum of hard x-ray emission from a plasma generated with femtosecond laser pulses with an intensity of 5 x 10(18) W/cm2 on a solid target. Measured and calculated angular distributions of x rays show a pronounced anisotropy for MeV photon energies. We complemented the spectral information by demonstrating a (gamm...
متن کاملTheoretical analysis of hard x-ray generation by nonperturbative interaction of ultrashort light pulses with a metal
The interaction of intense femtosecond pulses with metals allows for generating ultrashort hard x-rays. In contrast to plasma theories, tunneling from the target into vacuum is introduced as electron generation step, followed by vacuum acceleration in the laser field and re-entrance into the target to generate characteristic x-rays and Bremsstrahlung. For negligible space charge in vacuum, the ...
متن کاملX-ray imaging beyond the limits.
The intense, brief pulses of X-rays from upcoming free-electron lasers will greatly extend X-ray microscopy to the femtosecond time domain and to interatomic length scales. From recent experiments and simulations one can envisage imaging macromolecules with X-rays without the need for crystallization.
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...
