    • Correlation of photon pairs from the double Raman amplifier: Generalized analytical quantum Langevin theory 
      Ooi, C. H. Raymond; Scully, Marlan O.; Sun, Qingqing; Zubairy, M. Suhail (American Physical Society, 2007)
      We present a largely analytical theory for two-photon correlations G((2)) between Stokes (s) and anti-Stokes (a) photon pairs from an extended medium (amplifier) composed of double-Lambda atoms in counterpropagating geometry. ...
    • Electromagnetically induced transparency in rubidium vapor prepared by a comb of short optical pulses 
      Sautenkov, V. A.; Rostovtsev, Y. V.; Ye, C. Y.; Welch, George R.; Kocharovskaya, O.; Scully, Marlan O. (American Physical Society, 2005)
      It was shown by Kocharovskaya and Khanin [Sov. Phys. JETP 63, 945 (1986)] that a comb of optical pulses can induce a ground-state atomic coherence and change the optical response of an atomic medium. In our experiment, we ...
    • Entangled radiation via a Raman-driven quantum-beat laser 
      Qamar, Sajid; Al-Amri, M.; Qamar, Shahid; Zubairy, M. Suhail (American Physical Society, 2009)
      We propose a scheme for the entanglement generation of two cavity modes using a four-level Raman-driven quantum-beat laser (QBL). The atomic coherence is generated by a Raman-type two-photon process. Two different sufficient ...
    • High-order harmonic generation at a repetition rate of 100 kHz 
      Lindner, F.; Stremme, W.; Schatzel, M. G.; Grasbon, F.; Paulus, Gerhard G.; Walther, H.; Hartmann, R.; Struder, L. (American Physical Society, 2003)
    • Inversionless lasing with self-generated driving field 
      Belyanin, Alexey; Bentley, C.; Capasso, F.; Kocharovskaya, O.; Scully, Marlan O. (American Physical Society, 2001)
      We propose and study resonant ladder schemes of inversionless lasing on a fast-decaying transition when the population inversion is not possible or Very difficult to achieve. The driving field on a neighboring, slowly ...
    • Nonlinear magneto-optic polarization rotation with intense laser fields 
      Hsu, Paul S.; Patnaik, Anil K.; Welch, George R. (American Physical Society, 2008)
      We have studied the nonlinear Faraday effect with intense linear polarized light in an optically thick atomic rubidium vapor. We demonstrate that the polarization rotation rate (rotation angle per unit magnetic field, in ...
    • Nonlinear magneto-optical rotation of elliptically polarized light RID A-1272-2007 RID B-9041-2008 
      Matsko, A. B.; Novikova, I.; Zubairy, M. Suhail; Welch, George R. (American Physical Society, 2003)
      We predict theoretically and demonstrate experimentally an ellipticity-dependent nonlinear magneto-optic rotation of elliptically polarized light propagating in a medium with atomic coherence. We show that this effect ...
    • Quantum search protocol for an atomic array 
      Scully, Marlan O.; Zubairy, M. Suhail (American Physical Society, 2001)
      Quantum computers can, in principle, exceed the speed of ordinary computers by taking advantage of quantum coherence and entanglement. It is possible to find a "needle in a haystack" of N-1 straws in only rootN searches ...
    • Vacuum squeezing in atomic media via self-rotation RID A-1272-2007 RID B-9041-2008 
      Matsko, A. B.; Novikova, I.; Welch, George R.; Budker, D.; Kimball, D. F.; Rochester, S. M. (American Physical Society, 2002)
      When linearly polarized light propagates through a medium in which elliptically polarized light would undergo self-rotation, squeezed vacuum can appear in the orthogonal polarization. A simple relationship between self-rotation ...
