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…
Differential pumping for kHz operation of a Laser Wakefield accelerator based on a continuously flowing Hydrogen gas jet
Joséphine Monzac, Slava Smartsev, Julius Huijts +13
Laser-Wakefield Accelerators (LWFA) running at kHz repetition rates hold great potential for applications. They typically operate with low-energy, highly compressed laser pulses fo…
Continuous relativistic high-harmonic generation from a kHz liquid-sheet plasma mirror
Antoine Cavagna, Milo Eder, Enam Chowdhury +5
We report on continuous high-harmonic generation at 1 kHz repetition rate from a liquid-sheet plasma mirror driven by relativistic-intensity near-single-cycle light transients. Thr…
Beam Pointing of Relativistic High-order Harmonics Genrated on a Nonuniform Pre-plasma
Chaoneng Wu, Yiming Xu, Andre Kalouguine +8
The use of tunable pre-pulse is a common technique to enhance the high-order harmonic generation from surface plasma. The shape and dynamic of the electron density, the degree of i…
TW-class sub-2-cycle post-compression of Ti:Sapphire laser pulses in a gas-filled multipass cell
Louis Daniault, Jaismeen Kaur, Geoffrey Gallé +3
We report on the nonlinear temporal post-compression of 7 mJ sub-40 fs pulses from a commercial kHz Ti:Sapphire laser down to a record 4 fs duration (1.5 optical cycle) in a compac…
