Observation of picosecond superfluorescent pulses in rubidium atomic vapor pumped by 100-fs laser pulses
(American Physical Society, 2010)
We study the superfluorescence (SF) from a gas of rubidium atoms. The atoms of a dense vapor are excited to the 5D state from the 5S state by a two-photon process driven by 100-fs laser pulses. The atoms decay to the 6P ...
Subwavelength optical microscopy in the far field
(American Physical Society, 2011)
We present a procedure for subwavelength optical microscopy. The identical atoms are distributed on a plane and shined with a standing wave. We rotate the plane to different angles and record the resonant fluorescence ...
