Spectral-phase interferometry for direct electric-field reconstruction applied to seeded extreme-ultraviolet free-electron lasers [PDF]

, 2015
We present a setup for complete characterization of femtosecond pulses generated by seeded free-electron lasers (FEL's) in the extreme-ultraviolet spectral region.

Maximum brightness of linac-driven electron beams in the presence of collective effects

Physical Review Special Topics. Accelerators and Beams, 2013
Linear accelerators capable of delivering high brightness electron beams are essential components of a number of research tools, such as free electron lasers (FELs) and elementary particle colliders.

Ion laser plasmas [PDF]

, 1971
The typical noble gas ion laser plasma consists of a high-current-density glow discharge in a noble gas, in the presence of a magnetic field. Typical CW plasma conditions are current densities of 100 to 2000 A/cm^2, tube diameters of 1 to 10 mm, filling ...

Quantum interference effects in an ensemble of $^{229}$Th nuclei interacting with coherent light

, 2013
As a unique feature, the $^{229}$Th nucleus has an isomeric transition in the vacuum ultraviolet that can be accessed by optical lasers. The interference effects occurring in the interaction between coherent optical light and an ensemble of $^{229}$Th ...

Efficient Photoionization-Loading of Trapped Cadmium Ions with Ultrafast Pulses [PDF]

, 2006
Atomic cadmium ions are loaded into radiofrequency ion traps by photoionization of atoms in a cadmium vapor with ultrafast laser pulses. The photoionization is driven through an intermediate atomic resonance with a frequency-quadrupled mode-locked Ti ...

High-energy, high-peak-power, sub-nanosecond, spatial super-Gaussian 177 nm vacuum ultraviolet laser

High Power Laser Science and Engineering
A high-energy pulsed vacuum ultraviolet (VUV) solid-state laser at 177 nm with high peak power by the sixth harmonic of a neodymium-doped yttrium aluminum garnet (Nd:YAG) amplifier in a KBe2BO3F2 prism-coupled device was demonstrated. The ultraviolet (UV)

Bunch decompression for laser-plasma driven free-electron laser demonstration schemes

Physical Review Special Topics. Accelerators and Beams, 2013
X-ray free-electron lasers (FELs) require a very high electron beam quality in terms of emittance and energy spread. Since 2004 high quality electrons produced by laser-wakefield accelerators have been demonstrated, but the electron quality up to now did

High photon flux table-top coherent extreme ultraviolet source

, 2014
High harmonic generation (HHG) enables extreme ultraviolet radiation with table-top setups. Its exceptional properties, such as coherence and (sub)-femtosecond pulse durations, have led to a diversity of applications.

Frequency mixing in accelerator based sources and application to tunable seeded free-electron lasers

Physical Review Special Topics. Accelerators and Beams, 2014
In this article we address the problem of tunability of seeded free-electron lasers (FELs), working typically in the domain of the vacuum ultraviolet. The seeding of FELs with an external laser permits us to obtain FEL pulses with both good longitudinal ...
