Stable 50 MeV Beams from a 100 Hz Laser-Wakefield Accelerator Driven by an OPCPA Laser
S. Smartsev, J. Wheeler, O. Lundh +12
We demonstrate a laser-wakefield accelerator driven by a high-repetition-rate optical parametric chirped-pulse amplification (OPCPA) laser, producing stable, quasi-monoenergetic el…
Electron Acceleration in a Flying-Focus Laser Wakefield Accelerator
Aaron Liberman, Anton Golovanov, Slava Smartsev +3
Structured light pulses hold significant promise for their ability to overcome dephasing in laser-wakefield accelerators, that should facilitate applications in high-energy physics…
Demonstration of ultra-low emittance beams in a kHz laser wakefield accelerator and application to electron diffraction
J. Monzac, S. Smartsev, J. Huijts +12
We present a compact, cost-effective method for measuring the emittance of kHz-repetition-rate laser-wakefield accelerated electron beams using a permanent solenoid. The measured n…
First Electron Acceleration in a Tunable-Velocity Laser Wakefield
Aaron Liberman, Anton Golovanov, Slava Smartsev +3
We present the first experimental confirmation that a laser-wakefield accelerator produced by a flying focus pulse is able to maintain the coherent structures necessary to accelera…
First direct observation of a wakefield generated with structured light
Aaron Liberman, Anton Golovanov, Slava Smartsev +6
The use of structured light to control the phase velocity of the wake in laser-wakefield accelerators has generated significant interest for its ability to mitigate electron dephas…
Optical ionization effects in kHz laser wakefield acceleration with few-cycle pulses
Joséphine Monzac, Slava Smartsev, Julius Huijts +13
We present significant advances in Laser Wakefield Acceleration (LWFA) operating at a 1 kHz repetition rate, employing a sub-TW, few-femtosecond laser and a continuously flowing hy…
Simple few-shot method for spectrally resolving the wavefront of an ultrashort laser pulse
Slava Smartsev, Aaron Liberman, Igor A. Andriyash +10
We present a novel and straightforward approach for the spatio-spectral characterization of ultrashort pulses. This minimally intrusive method relies on placing a mask with special…
Use of spatiotemporal couplings and an axiparabola to control axial energy deposition velocity
Aaron Liberman, Ronan Lahaye, Slava Smartsev +5
This paper presents the first experimental realization of a scheme that allows for the tuning of the axial energy deposition velocity of a focal spot with relativistic intensity. B…
Spatiotemporal pulse characterization with far-field beamlet cross-correlation
Slava Smartsev, Sheroy Tata, Aaron Liberman +9
We present a novel, straightforward method for spatiotemporal characterization of ultra-short laser pulses. The method employs far-field interferometry and inverse Fourier transfor…
Controlled acceleration of GeV electron beams in an all-optical plasma waveguide
Kosta Oubrerie, Adrien Leblanc, Olena Kononenko +9
Laser-plasma accelerators produce electric fields of the order of 100 GV/m, more than 1000 times larger than radio-frequency accelerators. Thanks to this unique field strength, the…
Axiparabola: a new tool for high-intensity optics
Kosta Oubrerie, Igor A. Andriyash, Ronan Lahaye +3
An axiparabola is a reflective aspherical optics that focuses a light beam into an extended focal line. The light intensity and group velocity profiles along the focus are adjustab…
Hard X-rays from laser-wakefield accelerators in density tailored plasmas
Michaela Kozlova, Igor Andriyash, Julien Gautier +10
Betatron x-ray sources from laser-plasma accelerators combine compactness, high peak brightness, femtosecond pulse duration and broadband spectrum. However, when produced with Tera…
