Ponderomotive Achromat for Electron Optics: Radially Polarized Annular Focusing and a Round-Lens Corrector Regime
Yuuki Uesugi, Yuichi Kozawa
Ponderomotive electron optics has attracted attention because structured optical fields provide round-lens functionalities, including negative lens power and negative spherical abe…
Crossed Ponderomotive Lenses for Spherical Aberration Correction in Electron Optics
Yuuki Uesugi, Yuichi Kozawa
This article evaluates the lens characteristics of a non-rotationally symmetric electron lens based on a ponderomotive potential (i.e., a ponderomotive lens) formed by intersecting…
Properties of electron lenses produced by ponderomotive potential with Bessel and Laguerre-Gaussian beams
Yuuki Uesugi, Yuichi Kozawa, Shunichi Sato
The properties of electron round lenses produced by the ponderomotive potential are investigated in geometrical optics. The potential proportional to the intensity distribution of…
Electron round lenses with negative spherical aberration by a tightly focused cylindrically polarized light beam
Yuuki Uesugi, Yuichi Kozawa, Shunichi Sato
Free electrons moving in an optical standing wave field feel the ponderomotive potential, acting as a refractive-index medium in electron optics. Emerging technologies involving th…
Development of optical resonant cavities for laser-Compton scattering
T. Akagi, S. Araki, Y. Honda +12
We have been developing optical resonant cavities for laser-Compton scattering experiment at the Accelerator Test Facility in KEK. The main subject of the R&D is to increase laser…
Mode-locked pulse oscillation of a self-resonating enhancement optical cavity
Yuji Hosaka, Yosuke Honda, Atsushi Kosuge +6
A power enhancement optical cavity is a compelling means of realizing a pulsed laser with a high peak power and high repetition frequency, which is not feasible using a simple ampl…
