We report on the preflight spectral calibration of the first Orbiting Carbon Observatory (OCO) instrument. In particular, the instrument line shape (ILS) function as well as spectral position was determined experimentally for all OCO channels. Initial determination of these characteristics was conducted through laser-based spectroscopic measurements. The(More)
We demonstrate the production of micron-sized high-density atom clouds of interest for mesoscopic quantum information processing. We evaporate atoms from 60 !K, 3"1014 atoms/cm3 samples contained in a highly anisotropic optical lattice formed by interfering diffracted beams from a holographic phase plate. After evaporating to 1 !K by lowering the confining(More)
Ultracold Rb atoms were used to demonstrate nondegenerate four-wave mixing through a Rydberg state. Continuous 5S-5P-nD two-photon excitation to the Rydberg state was combined with an nD-6P tuned laser in a phase-matched geometry. The angular dependence, spatial profile, and dependence on detuning were investigated, showing good agreement with theory. Under(More)
This paper describes the radiometric calibration of the original Orbiting Carbon Observatory. The calibration process required characterizing both the dark current level and gain coefficients of each instrumental channel. The dark response was characterized with extensive testing and revealed some unexpected instrument behavior. The gain coefficients were(More)
We demonstrate the production of micron-sized high density atom clouds of interest for mesoscopic quantum information processing. We evaporate atoms from 60 μK, 3 × 10 atoms/cm samples contained in a highly anisotropic optical lattice formed by interfering diffracted beams from a holographic phase plate.
