Theoretical work relevant to the determination of values of the fundamental constants, tests of bound-state quantum electrodynamics (QED), and … more

Vacuum-Ultraviolet Optical Properties of Cryogenic Water Ices

The optical properties of cryogenic water ices in the vacuum-ultraviolet spectral range are studied. more

Calibration of the Extreme UV/X-ray Irradiance Sensor (EXIS) for the Geostationary Operations Environment Satellite R-Series Program (GOES-R)

Calibrations of the The Extreme ultraviolet/X-ray Irradiance Sensor (EXIS), which will be installed on the Geostationary Operations Environment … more

Extreme ultraviolet optical constants

In the vacuum ultraviolet and extreme ultraviolet (EUV), the indices of refraction of all materials become complex: N = n + ik , or N = 1- d + ik … more

Frequency Comb Spectroscopy

We use frequency combs based on ultrafast mode-locked lasers to perform precision spectroscopy in the near- and mid-infrared domains, for rapid, … more

Frequency Comb Calibration of Astronomical Spectrographs

We have constructed portable frequency combs that have provided in situ calibration of astronomical spectrographs, to aid in the search for … more
