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…
Frequency comb vernier spectroscopy in the near infrared
F. Zhu, J. Bounds, A. Bicer +5
We perform femtosecond frequency comb vernier spectroscopy in the near infrared with a femtosecond Er doped fiber laser, a scanning high-finesse cavity and an InGaAs camera. By uti…
Filament propagation length of femtosecond pulses with different transverse modes
N. Kaya, M. Sayrac, G. Kaya +3
We experimentally studied intense femtosecond pulse filamentation and propagation in water for Gaussian, Laguerre-Gaussian, and Bessel-Gaussian incident beams. These different tran…
Intensity-Resolved Above Threshold Ionization of Xenon with Short Laser Pulses
Nathan A. Hart, James Strohaber, Gamze Kaya +3
We present intensity-resolved above threshold ionization (ATI) spectra of xenon using an intensity scanning and deconvolution technique. Experimental data were obtained with laser…
High-power mid-infrared frequency comb source based on a femtosecond Er:fiber oscillator
Feng Zhu, Holger Hundertmark, Alexandre A. Kolomenskii +3
We report on a high-power mid-infrared frequency comb source based on a femtosecond Er:fiber oscillator with a stabilized repetition rate at 250 MHz. The mid-infrared frequency com…
Avoided Crossing Patterns and Spectral Gaps of Surface Plasmon Modes in Gold Nano-Structures
Alexandre Kolomenskii, Siying Peng, Jeshurun Hembd +4
The transmission of ultrashort (7 fs) broadband laser pulses through periodic gold nano-structures is studied. The distribution of the transmitted light intensity over wavelength a…
Ultrashort intense-field optical vortices produced with laser-etched mirrors
J. Strohaber, T. Scarborough, C. J. G. J. Uiterwaal
We introduce a simple and practical method to create ultrashort intense optical vortices for applications involving high-intensity lasers. Our method utilizes femtosecond laser pul…
