Multimode regimes in quantum cascade lasers: From coherent instabilities to spatial hole burning RID B-8648-2009
(American Physical Society, 2008)
A theoretical and experimental study of multimode operation regimes in quantum cascade lasers (QCLs) is presented. It is shown that the fast gain recovery of QCLs promotes two multimode regimes: One is spatial hole burning ...
Measurements and calculations of metastable level lifetimes in Fe X, Fe XI, Fe XII, Fe XIII, and Fe XIV
(American Physical Society, 2001)
Lifetimes of metastable levels in the ground term of Fe ions within the 3s(2)3p(k), k=1-5, isoelectronic sequences have been measured. These measurements were performed utilizing ions that were selected by mass to charge ...
Quantum-state measurement of two-mode entangled field-state in a high-Q cavity RID C-6638-2008
(American Physical Society, 2005)
We propose a scheme for the measurement of a two-mode entangled field-state in a high-Q cavity. The scheme utilizes the momentum distribution spectrum in the Raman-Nath regime of a three-level atom in V configuration. Due ...
Quantum teleportation of four-dimensional qudits
(American Physical Society, 2010)
A protocol for the teleportation of arbitrary quantum states of four-dimensional qudits is presented. The qudit to be teleported is encoded in the combined state of two ensembles of atoms placed in a cavity at the sender's ...
Compensation of ac Stark shifts in optical magnetometry RID B-9041-2008 RID A-1272-2007
(American Physical Society, 2001)
The ac Stark shift of the resonance frequency of the nonlinear magneto-optic effect (NMOE) results in a fundamental broadening of this resonance which limits the precision of optical magnetometry based on NMOE. We have ...
Nonlinear magneto-optical rotation of elliptically polarized light RID A-1272-2007 RID B-9041-2008
(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 ...
Theory of femtosecond coherent anti-Stokes Raman backscattering enhanced by quantum coherence for standoff detection of bacterial spores
(American Physical Society, 2005)
Backscattered signal of coherent anti-Stokes Raman spectroscopy can be an extremely useful tool for remote identification of airborne particles, provided the signal is sufficiently large. We formulate a semiclassical theory ...
Role of noise operators on two-photon correlations in an extended coherent Raman medium
(American Physical Society, 2007)
An extended medium driven in a double Raman configuration generates Stokes and anti-Stokes fields that are described by coupled parametric oscillator equations with solutions that depend on input boundary operators and ...
Distilling two-atom distance information from intensity-intensity correlation functions RID A-5077-2009
(American Physical Society, 2006)
The intensity-intensity correlation function of the resonance fluorescence light of two two-level atoms driven by a resonant standing-wave laser field is examined. Our aim is to gain information on the distance between the ...
