A thermoelastic limit on the focal intensity in Fabry-Pérot cavities
Jeremy J. Axelrod, Lothar Maisenbacher, Ashwin Singh +4
Light in the mode of a Fabry-Pérot cavity heats the mirror surfaces via optical absorption, causing thermoelastic deformation of the mirror substrates, which in turn dictates the s…
Crossed laser phase plates for transmission electron microscopy
Petar N. Petrov, Jessie T. Zhang, Jeremy J. Axelrod +2
For decades since the development of phase-contrast optical microscopy, an analogous approach has been sought for maximizing the image contrast of weakly-scattering objects in tran…
A Laser Phase Plate for Transmission Electron Microscopy
Jeremy J. Axelrod
Low image contrast is a major limitation in transmission electron microscopy, since samples with low atomic number only weakly phase-modulate the illuminating electron beam, and be…
Modern approaches to improving phase contrast electron microscopy
Jeremy J. Axelrod, Jessie T. Zhang, Petar N. Petrov +2
Although defocus can be used to generate partial phase contrast in transmission electron microscope images, cryo-electron microscopy (cryo-EM) can be further improved by the develo…
Dynamics of a buffer-gas-loaded, deep optical trap for molecules
Ashwin Singh, Lothar Maisenbacher, Ziguang Lin +3
We describe an approach to optically trapping small, chemically stable molecules at cryogenic temperatures by buffer-gas loading a deep optical dipole trap. The ~10 K trap depth wi…
High-Power Near-Concentric Fabry-Perot Cavity for Phase Contrast Electron Microscopy
Carter Turnbaugh, Jeremy J. Axelrod, Sara L. Campbell +8
Transmission electron microscopy (TEM) of vitrified biological macromolecules (cryo-EM) is limited by the weak phase contrast signal that is available from such samples. Using a ph…
Observation of the relativistic reversal of the ponderomotive potential
Jeremy J. Axelrod, Sara L. Campbell, Osip Schwartz +3
The secular dynamics of a non-relativistic charged particle in an electromagnetic wave can be described by the ponderomotive potential. Although ponderomotive electron-laser intera…
Laser control of the electron wave function in transmission electron microscopy
O. Schwartz, J. J. Axelrod, S. L. Campbell +3
Laser-based preparation, manipulation, and readout of the states of quantum particles has become a powerful research tool that has enabled the most precise measurements of time, fu…
Continuous 40 GW/cm laser intensity in a near-concentric optical cavity
Osip Schwartz, Jeremy J. Axelrod, Philipp Haslinger +3
Manipulating free-space electron wave functions with laser fields can bring about new electron-optical elements for transmission electron microscopy. In particular, a Zernike phase…
