Observation of precursorlike behavior of femtosecond pulses in a dye with a strong absorption band
(American Physical Society, 2011)
Recent interest in Sommerfeld-Brillouin optical precursors has brought attention to the possibility of optical precursor observation in bulk matter. We investigate the possible formation of optical precursors in an organic ...
Momentum distributions of sequential ionization generated by an intense laser pulse
(American Physical Society, 2011)
The relative yield and momentum distributions of all multiply charged atomic ions generated by a short (30 fs) intense (10(14)-5 x 10(18) W/cm(2)) laser pulse are investigated using a Monte Carlo simulation. We predict a ...
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 ...
Propagation dynamics of controlled cross-talk via interplay between chi((1)) and chi((3)) processes
(American Physical Society, 2011)
We investigate theoretically and experimentally the propagation dynamics of a nonlinear cross-talk effect between two probe channels in a double-ladder system and show that an interplay between chi((1)) and chi((3)) processes ...
Gaussian-state entanglement in a quantum beat laser
(American Physical Society, 2011)
Recently quantum beat lasers have been considered as a source of entangled radiation [S. Qamar, F. Ghafoor, M. Hillery, and M. S. Zubairy, Phys. Rev. A 77, 062308 (2008)]. We investigate and quantify the entanglement of ...
Controllable optical switch using a Bose-Einstein condensate in an optical cavity
(American Physical Society, 2011)
The optical bistability of an ultracold atomic ensemble located in a small-volume ultrahigh-finesse optical cavity is investigated. We find that a transverse pumping field can be used to control the bistable behavior of ...
