General relativistic manifestations of orbital angular and intrinsic hyperbolic momentum in electromagnetic radiation
James Strohaber
General relativistic effects in the weak field approximation are calculated for electromagnetic Laguerre-Gaussian (LG) beams. The current work is an extension of previous work on t…
Optical device for the precision control of the electric field in the focus of a beam
James Strohaber
We present an inline optical device consisting of four optical components that produce a laser field consisting of two sub-beams where one is radially polarized and the other is li…
A perturbative quantized twist embedded in Minkowski spacetime
James Strohaber
In this article, spatially-structured gravitational waves are investigated. Drawing upon analogies between electrodynamics and general relativity, a new gauge is found. We investig…
Selective Strong-Field Enhancement and Suppression of Ionization with Short Laser Pulses
Nathan A. Hart, James Strohaber, Alexandre A. Kolomenskii +3
We experimentally demonstrate robust selective excitation and attenuation of atomic Rydberg level populations in sodium vapor (Na I) using intense laser pulses in the strong field…
Highly ionized xenon and volumetric weighting in restricted focal geometries
J. Strohaber, A. A. Kolomenskii, H. A. Schuessler
The ionization of xenon atoms subjected to 42fs, 800nm pulses of radiation from a Ti:Sapphire laser was investigated. In our experiments a maximum laser intensity of $\sim2\times 1…
