Rubidium is a solid metal at room temperature and has an optimum vapour pressure for at about 35"c, good signals being available within the range 25-45"~. At higher temperatures (-500~) it is possible to produce self-oscillation in the 87Rb isotope, but no interference with the 8sRb signal occurs at temperatures below 45"c.

All-Optical Switching in Rubidium Vapor | Science

Apr 29, 2005· We report on an all-optical switch that operates at low light levels. It consists of laser beams counterpropagating through a warm rubidium vapor that induce an off-axis optical pattern. A switching laser beam causes this pattern to rotate even when the power in the switching beam is much lower than the power in the pattern. The observed switching energy density is very low, suggesting …

We report observation of query pulse length dependent Ramsey interference (QPLD-RI), using pulsed Raman excitation in rubidium vapor. This is observed when a long, attenuated query pulse is used during pulsed Raman excitation. We explain the physical mechanism behind the QPLD-RI using a Bloch vector model. We also use numerical solutions to time-dependent density matrix equations to simulate ...
