Prelaunch absolute, SI-traceable radiometric calibration of satellite-based sensors is key to ensuring the utility of imaging spectrometer-based data products. The development of detector-based calibration techniques leads to the feasibility of meeti

Solar radiation-based calibration (SRBC) has been used to assess radiometric calibration of earth remote sensing sensors using a source with the same spectral source that is expected during the instrument's operation. The approach has been shown capa

We observe the acceleration of electron bunches with a Lorentzian transverse profile using few-cycle laser pulses focused on the downstream side of a near-critical hydrogen gas jet.

We demonstrate interferometric measurements of plasma formed by a laser pulse above the relativistic self-focusing power for near-critical density plasmas using a third harmonic probe.

We demonstrate laser wakefield acceleration of quasi-monoenergetic electron bunches up to 15 MeV at 1 kHz repetition rate with 2.5 pC charge per bunch and a core with < 7 mrad beam divergence. Acceleration is driven by 5 fs, < 2.7 mJ laser pulses inc

The injection of electrons into a laser wakefield accelerator (LWFA) is observed to generate an intense coherent ultra-broadband and ultrashort pulse radiation flash, consistent with the acceleration of electrons from rest to nearly the speed of ligh

We measure the nonlinear refractive indices of major air constituents (N2, O2, Ar) in the wavelength range of λ = 2.5μm−10.6μm, extending the range of prior measurements [1]. These results are important for the study of intense laser propagation

We report on, to the best of our knowledge, the first results of laser plasma wakefield acceleration driven by ultrashort mid-infrared (IR) laser pulses (λ=3.9 μm, 100 fs, 0.25 TW), which enable near- and above-critical density interactions with mo

We demonstrate laser driven acceleration of electrons to MeV scale energies at 1 kHz repetition rate using few mJ pulse energies focused on near critical density He and H2 gas jets.
