Optical Precursor in Hot Rubidium Vapor - NASA/ADS

A pico-second pulse with center wavelength about 795nm was sent through a hot rubidium (Rb) cell. The output pulse was detected by a streak camera with 2 pico-second resolution. The experiment data showed the original pulse separates to a main pulse and a precursor which travels faster than the main pulse. This gives some experiment evidence of the formation of precursor when a step-function ...

Storage and retrieval of ghost images in hot atomic vapor

Since ghost imaging requires (quantum or classical) multimode spatial correlation between two beams of light, our experiment shows that the spatially multimode correlation, a second-order correlation property of light, can indeed be preserved during the storage-retrieval process.

Rubidium standard - Wikipedia

Synopsis. The Rb standard is the most inexpensive, compact, and widely produced atomic clock, used to control the frequency of television stations, cell phone base stations, in test equipment, and global navigation satellite systems like GPS.Commercial rubidium clocks are less accurate than caesium atomic clocks, which serve as primary frequency standards, so the rubidium clock is a secondary ...
