Micro-sized tunable liquid crystal optical filters
Caleb Stoltzfus, Russell Barbour, David Atherton +1
Liquid Crystal Arrayed Microcavities (LCAM) is a new technology for ultra-narrow optical filtering (FWHM ~ 0.1 nm) that uses pico-liter volume Fabry-Perot type optical cavities fil…
Multi-Dimensional, Non-Contact Metrology using Trilateration and High Resolution FMCW Ladar
Ana Baselga Mateo, Zeb W. Barber
Here we propose, describe, and provide experimental proof-of-concept demonstrations of a multi-dimensional, non-contact length metrology system design based on high resolution (mil…
Precision and Accuracy Testing of FMCW Ladar Based Length Metrology
Ana Baselga Mateo, Zeb W. Barber
The calibration and traceability of high resolution frequency modulated continuous wave (FMCW) ladar sources is a requirement for their use in length and volume metrology. We repor…
Hyper-Ramsey Spectroscopy of Optical Clock Transitions
V. I. Yudin, A. V. Taichenachev, C. W. Oates +6
We present non-standard optical Ramsey schemes that use pulses individually tailored in duration, phase, and frequency to cancel spurious frequency shifts related to the excitation…
Spin-1/2 Optical Lattice Clock
N. D. Lemke, A. D. Ludlow, Z. W. Barber +7
We experimentally investigate an optical clock based on Yb () atoms confined in an optical lattice. We have evaluated all known frequency shifts to the clock transit…
Compensation of Field-Induced Frequency Shifts in Ramsey Spectroscopy of Optical Clock Transitions
A. V. Taichenachev, V. I. Yudin, C. W. Oates +6
We have extended Ramsey spectroscopy by stepping the probe frequency during the two Ramsey excitation pulses to compensate frequency shifts induced by the excitation itself. This m…
