Fabrication, testing, and assembly of high-finesse optical fiber microcavity for molecule cavity QED experiment

High-finesse AlxOy/AlGaAs nonabsorbing optical cavity

Fluctuating nanomechanical system in a high finesse optical microcavity.

The idea of extending cavity quantum electrodynamics experiments to sub-wavelength sized nanomechanical systems has been recently proposed in the context of optical cavity cooling and optomechanics of deformable cavities. Here we present an experiment involving a single nanorod consisting of about 10(9) atoms precisely positioned into the confined mode of a miniature high finesse Fabry-Pérot mi...

Medium-finesse optical cavity for the stabilization of Rydberg lasers.

We describe the design, construction, and characterization of a medium-finesse Fabry-Perot cavity for simultaneous frequency stabilization of two lasers operating at 960 and 780 nm wavelengths, respectively. The lasers are applied in experiments with ultracold rubidium Rydberg atoms, for which a combined laser linewidth similar to the natural Rydberg linewidth (≈10  kHz) is desired. The cavity,...

Microcomb design and fabrication for high accuracy optical assembly

There are two popular optic designs for x-ray space telescopes: the traditional monolithic design, which has demonstrated subarcsecond resolution but at enormous weight and cost per collecting area, and the foil design, which has achieved far greater collecting area per weight and cost, but with resolution limited to the arcminute level, in part due to foil assembly inaccuracy. In this article,...
