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 ...
Optical imaging beyond the diffraction limit via dark states RID A-8711-2009
(American Physical Society, 2008)
We study the possibility of creating spatial patterns having subwavelength size by using the so-called dark states formed by the interaction between atoms and optical fields. These optical fields have a specified spatial ...
