Terahertz-optical intensity grating for creating high-charge, attosecond electron bunches
J. Lim, Y. D. Chong, L. J. Wong
Ultrashort electron bunches are useful for applications like ultrafast imaging and coherent radiation production. Currently, however, the shortest achievable bunches, at attosecond…
Laser-Induced Linear Electron Acceleration in Free Space
Liang Jie Wong, Kyung-Han Hong, Sergio Carbajo +5
Linear acceleration in free space is a topic that has been studied for over 20 years, and its ability to eventually produce high-quality, high energy multi-particle bunches has rem…
A Threshold for Laser-Driven Linear Particle Acceleration in Unbounded Vacuum
Liang Jie Wong, Franz X. Kärtner
We hypothesize that a charged particle in unbounded vacuum can be substantially accelerated by a force linear in the electric field of a propagating electromagnetic wave only if th…
Direct acceleration of an electron in infinite vacuum by a pulsed radially-polarized laser beam
Liang Jie Wong, Franz X. Kärtner
We study the direct acceleration of a free electron in infinite vacuum along the axis of a pulsed radially-polarized laser beam. We find that net energy transfer from laser pulse t…
Two-Color-Laser-Driven Direct Electron Acceleration in Infinite Vacuum
Liang Jie Wong, Franz X. Kärtner
We propose a direct electron acceleration scheme that uses a two-color pulsed radially-polarized laser beam. The two-color scheme achieves electron acceleration exceeding 90% of th…
Compact electron acceleration and bunch compression in THz waveguides
Liang Jie Wong, Arya Fallahi, Franz X. Kärtner
We numerically investigate the acceleration and bunch compression capabilities of 20 mJ, 0.6 THz-centered coherent terahertz pulses in optimized metallic dielectric-loaded cylindri…
