Coherent 455 nm beam production in a cesium vapor.
نویسندگان
چکیده
We observe coherent, cw, 455 nm blue-beam production via frequency upconversion in cesium vapor. Two IR lasers induce strong double excitation in a heated cesium vapor cell, allowing the atoms to undergo a double cascade and produce a coherent, collimated, blue beam copropagating with the two IR pump lasers.

Blue five-level lasing-without-inversion system in rubidium
We demonstrate continuous coherent blue laser light production using a five-level lasing-without-inversion scheme in rubidium vapor. Two low-power lasers at 780 nm and 776 nm induce a strong atomic coherence in the 5S-5P-5D states. The atoms decay to the 6P excited state from which stimulated emission produces a coherent blue (420 nm) beam. We have coupled both ground-state hyperfine levels, ef...
متن کاملObservation of Hydrogen and Cesium Spectra in a Negative Ion Source for a Neutral Beam Injector using a Multi-Channel Spectrometer
Effective production of hydrogen negative ions (H−) is one of the important issues in high power neutral beam injection (NBI) for fusion experimental devices. Cesium (Cs) vapor is seeded in the H− sources to enhance the H− production rate, which depends strongly on the amount of Cs inside the source. On the other hand, oxygen and water attenuate the production rate. In order to investigate the ...

We demonstrate production of continuous coherent blue laser light by using a five-level system in rubidium vapor. Two low-power lasers, at 780 and 776 nm, induce strong atomic coherence in the 5S-5P-5D states. The atoms decay to the 6P excited state, from which stimulated emission produces a coherent blue (420 nm) beam. We have coupled both ground-state hyperfine levels, effecting coherence bet...
متن کاملMicrofabricated alkali atom vapor cells
We describe the fabrication of chip-sized alkali atom vapor cells using silicon micromachining and anodic bonding technology. Such cells may find use in highly miniaturized atomic frequency references or magnetometers. The cells consist of cavities etched in silicon, with internal volumes as small as 1 mm. Two techniques for introducing cesium and a buffer gas into the cells are described: one ...
متن کاملEnhanced frequency up-conversion in Rb vapor.
We demonstrate highly efficient generation of coherent 420 nm light via up-conversion of near-infrared lasers in a hot rubidium vapor cell. By optimizing pump polarizations and frequencies we achieve a single-pass conversion efficiency of 260% per Watt, significantly higher than in previous experiments. A full exploration of the coherent light generation and fluorescence as a function of both p...
