Laser Spectroscopy with Nanometric Cells Containing Atomic Vapor of Metal: Influence of Buffer Gas
Comparison of absorption and fluorescence in a nano-cell containing Rb vapor with other Rb nano-cells where neon gas is added is presented. The effect of collapse and revival of Dicke-type narrowing is still observable for the Rb nano-cells where Ne gas is added under 6 and 20 Torr pressure for the thickness L=/2 and L=, where is a resonant laser wavelength 794 nm (D1 line). Particularly fo...
متن کاملLong-lived qubit memory using atomic ions.
We demonstrate experimentally a robust quantum memory using a magnetic-field-independent hyperfine transition in 9Be+ atomic ion qubits at a magnetic field B approximately = 0.01194 T. We observe that the single physical qubit memory coherence time is greater than 10 s, an improvement of approximately 5 orders of magnitude from previous experiments with 9Be+. We also observe long coherence time...
متن کاملBuffer-gas-induced absorption resonances in Rb vapor
We observe transformation of the electromagnetically induced transparency (EIT) resonance into an absorption resonance in a L interaction configuration in a cell filled with Rb and a buffer gas. This transformation occurs as one-photon detuning of the coupling fields is varied from the atomic transition. No such absorption resonance is found in the absence of a buffer gas. The width of the abso...
متن کاملQuantum memory in warm rubidium vapor with buffer gas.
The realization of quantum memory using warm atomic vapor cells is appealing because of their commercial availability and the perceived reduction in experimental complexity. In spite of the ambiguous results reported in the literature, we demonstrate that quantum memory can be implemented in a single cell with buffer gas using the geometry where the write and read beams are nearly copropagating...
متن کاملIntense atomic and molecular beams via neon buffer-gas cooling
We realize a continuous, intense, cold molecular and atomic beam source based on buffer-gas cooling. Hot vapor (up to 600K) from an oven is mixed with cold (15K) neon buffer gas, and then emitted into a high-flux beam. The novel use of cold neon as a buffer gas produces a forward velocity distribution and low-energy tail that is comparable to much colder helium-based sources. We expect this sou...
